Brace stamped a lot of his stuff, including postcards, which is likely why the seller knows who made it. I searched, and the seller of the first pc is selling a ton of 1950s-60s baseball postcards, so perhaps he knows. Perhaps he got them all from a single old collection. He never shows the backs, by the way. I don't know when Brace made poscards-- perhaps someone, including the seller, does. That info may help. I recommend asking the seller about the postcard.

Brace reprinted his and others images a lot over the years-- that was his business--, so it's hard to date his photos. Except, his old photos are usually easier to id, due to the old stamp, zip code and old look (toning, etc). But a lot his stuff can be harder to pinpoint.

In recent years, his wife made photos from his images. However, from what I've seen, they have a different stamp and are on clearly modern photopaper (modern kodak branding). A lot of these photos are color. In fact, all the ones I saw were of modern player-- no Lou Gehrig reprints.

I've had Brace's photos and some Rowe photos, but never any postcards by either, so have no hands on experience or much knowledge about their postcards.

All I can add is the Brace and Rowe postcards are inexpensive. The seller of the first one has a BIN of $100 which is about 10x higher than value.
