How do I know if this ad is vintage?

These are believed to be authentic to the time period. There was a very large find of these (and many similar H & B Ad posters) about a decade ago. They are still pretty common, and at the time could be picked up very cheap.

Since the value is not high, it is probably not likely something that would be re-produced or faked. They are actually pretty neat, given the fact that they're reasonably priced (and original).

Real or repro it's a neat piece!!

Great looking piece but one has to wonder why they would show a Ferris Fain model bat instead of a Ted Williams model!! I mean if you have a huge star name why not use his bat as well.

About 5-6 years ago I bought several advertisements that came from this find. I was told this was a full set of what was found. They were all baseball signs similar to the one you posted. I assumed they were the real deal but never knew for sure. Very very reasonably priced IMHO.

Perhaps Fain was featured since he won back to back batting titles in '51 & '52
