This will be obvious to many of us but I thought I would point it out just in case.
There is an ebay auction
Lot of (29) 1933 Goudey Big League Chewing Gum Baseball cards w/ Ruth & Hubbell that is full of reprints. On the back of every card where the word reprint should be there is a convenient scratch out.
In the description the seller puts:
"...this is what eBay was like back in the good days. Draw your own conclusions from images provided. If they don’t appear correct to you, please don’t bid or blow up my inbox. If they look good to you, bid away..."
