1923 W515 Strip Card Set

The W515's are commonly faked and thus collectors need to be aware of the variations.  Here's one I pulled off Etsy (which is a notable place for the fakes to be sold, often as 'vintage antiqued' cards.  This is some sort of art form I guess, but just shielding a great way for scammers to get their hands on some good looking reprints.

For the untrained eye, this card might look pretty real to most, but the paper is way too light in color, and of course the edges way to crisp and clean.  But of course an 'antiquer' could take this card and do some work on it (usually soaking in tea or other liquids) to give it an aged look.  Those are very easy to spot and look like little spider webs all over the card.
