Collecting signed government postcards (GPCs) - Questions for collectors

[americana_collector]

Hello

I’m new to the forum, but not new to collecting. I have diverse interests across several fields, but I’ve always had an interest in vintage baseball cards and baseball autographs. This year I’ve focused very heavily on signed government postcards (GPCs) and they have become my favorite medium of autograph collecting. I think it’s the simplicity and uniformity of the medium that appeals to me. I also like that they are postmarked/dated. For some reason I never focused on them until this year. Anyway, I assume I’m not alone in this interest and I joined the forum to ask a few questions of fellow collectors. Thank you for the time to read and respond.

1. Are there collectors who focus exclusively, or primarily, on GPCs?
2. What are some of your favorite collecting themes (i.e. HOFers, deadball
era players, etc.)?
3. What are the demographics of the average collector? (Full disclosure,
I’m late 30s).
4. Do you think there are still a number of original owner collections out
there? I’m thinking of individuals who were born in the 1930s or 1940s
and sought autographs TTM in the 1940s and 1950s? I know Leland’s
auctioned a large collection from R. Sklar in 2023.
5. When did the GPC form of collecting die out? I have had a very hard
time of finding players who came up in the late 1950s/early 1960s on
GPCs from that period.
