Opinions wanted on this 1934 Babe Ruth in Japan postcard

[dbrown]

There's a ton of these cards, definitely not issued in 1934 (in my opinion). I think 1960s (maybe 50s? maybe 70s?) is probably a good estimate. I've had a couple, stock is much thinner than 1930s postcards, printing process is different, design of the reverse is also not-1930s.

Of note: an example was in a Christies auction in late 2020, listing originally made the common assertion that it was from 1934, that dating was later changed:
"Please note a dating change for this lot. Undated, possibly modern era. This lot is now offered without a reserve."

That doesn't feel like a move Christie's would make without serious doubts.

That's about as much of an "official" note that it's a later issue as I can find. Postcard dealers (at least in the before covid times) priced this card low (the one I remember buying was something like $25 5 years ago), which is much better proof that it is not rare and not 1930s. Looks like those days are over, with PSA grading them and dealers pretending they are vintage.

Have you looked at this under blacklight?
