Here ya go!
http://shop.hobbiesdepot.com/searchquic ... PKT-5x7%22I tried photo albums and they got to be too bulky so that they wouldn't close. We had a discussion about this a few months back and Zombie Guide recomended post-card holders - so I ordered some on eBay but what I received wasn't what I had in mind - they were the wrong kind (singles instead of binder sleeves).
However, a few months back when at a Flea Market on Lincoln Hwy in Chambersburg, PA I came across a dealer that had a slew of binder storage products - for baseball cards, coins, and even POSTCARDS! They were perfect. So I took a picture of the brand name of the card holders so I could post it here. But some ass stole my cellphone before I posted it and that photo is lost to history.
I've had a hard time finding the original brand I saw at the flea market but the ones linked to above appear to be just as good. I can tell you that photo-albums don't work because the thickness of the cards will prvent the album from closing. But these postcard holders inserted into a D-size binder will be ideal.
