The PSA one is obviously labelled incorrectly. I would bet there is no ad on the back. The other Aldridge could be a W573 or V61 (type 1 or 2) as they both have the same fronts....
The only way to distinguish a W573 from a V61(either series) is to see the back. If it is blank it's probably a W573, though they are on thinner paper anyway, and if there is a Neilson's ad then it's a V61. I have not seen W573's with any fake (or real) backs though there could be some. Here are few W573's with ad backs....There aren't too many though and, as I said before, most of these type ad back cards are W575-1s, which Burdick actually classified as having various backs. Being a bit of a purist I classify most of the E121 ad back cards (not American Caramel but others) as W575-1. regards
