Help identifying these 1966 topps prints?
 

Have been sorting through my dads massive card collection over the last few years. thousands and thousands of cards from the 50s/60s. yesterday i came across a binder that had these in them, they seem to be authentic to the 60s but cant find anything on ebay to comp them with. the backs are empty and there are crease lines like they had once been folded. Figured id ask the pros, anyone know what these are? regular baseball card there for size reference. thanks!

they are 1967 Topps Pin Ups (came folded in packs)....You can check eBay for what they sell for (somewhat common)

and thats what i was looking for, thank you!

Check Sportlots.com
 

That's an impressive collection. You can check the 1967 Topps Insert Posters on Sportslots.com to find what they are being sold for.

Hold them up to the light and see if there is a small pinhole in the very middle. Most have the hole which effects the value. Very hard to find clean, centered, no tears and no holes.
Pristine HOFers examples can fetch good money in high grade.
