So that's what the new ones look like. Thanks for posting.
Does anybody know where I can purchase an April 12, 1945 envelope postmarked Warm Springs, Georgia? I've been looking for an awful long time.
These may very well be non-existent. Warm Springs is a tiny village, less than 500 population, even today. FDR died early in the afternoon and I'm sure the town shut down once the news got out. So only mail processed that morning would have been cancelled on 4/12/45. That's a very narrow window of opportunity. In DC there was more time and motivated stamp dealers.
