The FDCs found in the current survey census were obtained by examining auction catalogues, stocks of cover dealers, eBay and other auction sites, and solicited lists from FDC collectors. The catalogues were looked at more than once as critical knowledge was being accumulated regarding the identification of Hammelman covers. There has been no attempt to accumulate counts of specific covers since the survey is interested in uniqueness, not quantity or scarcity. This decision was influenced by the magnitude of the survey, the fact that many auction FDCs appear similar in appearance, and that some FDCs appear in multiple auctions over the years. The analysis is based only on the covers in the survey. There is no way of knowing how Hammelman covers that have not survived could have affected the analysis. Please note that the survey is an ongoing effort and that the census is updated whenever new data is discovered.
The survey covers are found in an appendix. Each entry consists of a unique Scott Number/addressee combination that can represent one or more covers in a specific handwriting or typing style. Found in the entry from left to right are its Scott Number, First Day date, the handwriting or typing code, and the addressee and their city and state address. The sequence is by Scott Number. As mentioned previously, only covers identified by H1, H2, or T are included in the appendix or the analysis. The names on the covers are usually formally addressed with Mr., Mrs., or Miss. Many of the surnames are represented by first and middle initials.
The appendix is subdivided by Scott Number as follows:
Part 4 contains air mail, special delivery, parcel post, etc. covers.
The Survey Covers
There are 289 covers in the appendix. They contain 168 different Scott Numbers that span ordinary issues, commemoratives, air posts, special delivery, parcel post, and stamped envelopes. The First Days range from January 1, 1913 through March 15, 1935.
The covers were primarily sent to addresses in the Washington, DC area; about eighty percent in Washington, the remainder in nearby Maryland and northern Virginia. Henry seldom addressed covers to himself, but primarily used his friends as recipients.
Henry was rather consistent in preparing FDCs for new issues from 1913 through 1927. There are only a few gaps in the appendix and I expect that FDCs will surface that will eliminate them. The missing issues are Scott 581, 599, 632a, 635a, 638, C1-C3, and E11. It’s a different story after 1927. Many of the new issues from 1928 to 1934 are missing. (Conspicuous among the missing are the Kansas-Nebraska overprint issues from 1929.) Why? Cacheted FDCs were catching on and Henry never made the transition. His interest in FDCs was being superseded by his interest in FFCs. Many of Henry’s FDCs that survived after 1928 are found with add-on cachets. It is highly likely that many of his uncacheted covers of that period, because of their less desirable collectibility, were disposed of when Henry left the cover business.
There are 76 different names on the covers in the appendix. They break down into five groupings: philatelic associates, Henry’s residences, the Siebold residences, Henry’s USPOD associates, and miscellaneous. Whenever possible, I have listed a first name rather than just an initial.
The first grouping includes Henry’s philatelic friends and out-of-town dealers to whom he sent FDCs. Siebold could be considered part of this group, but because of his special relationship with Henry and the nature and volume of covers send to his residences, he represents a separate grouping.
Henry resided at a boarding house at 8 Seventh Street in Washington for several years. All of the known FFCs addressed to him were received at this address or his earlier Siebold address at 213 Florida Avenue. Henry sent several FDCs to other people at this address. Many of these are addressed to his landlady, Mrs. Annie Aman, and her daughters Emma and Sara. Henry continued this practice when the ownership of the boarding house changed in 1926 and the new landlady was Mrs. Holtzclaw. Her son Randolph received covers, in quantity, for at least four FDC issues and several FFCs. Another boarder, Fred Ludwig, received all of Henry’s Scott 549 FDCs. Harry Williams, who resided at Henry’s Maryland address, received a CE1 FDC in 1934.
Most of the FDCs sent to the Siebold residences are addressed to William and Marie. Henry also sent covers to a handful of other names at the Siebold residence on New York Avenue. These never exceeded more than one issue per name.
There are 45 USPOD employees in the USPOD grouping. They received covers at their employment offices and/or home addresses.
The miscellaneous grouping includes names that I have not been able to fit into the other groupings. Table of Names
