I'm trying to collect good images/scans/documentation of any and all stickers or paper signage that were included with Bally SS games to aid in making reproductions. I'm starting with 1981 games, since that is one I own. Below are a couple of cards/stickers that were missing from my game that I am planning to make reproductions of. Does anyone have others? Happy to share stickers/cards once they get made. Here's a couple of examples of designs in progress...

I have checked out http://www.pinballrebel.com/pinball/cards/ before (assuming that is the one you meant). But that site doesn't have source images as reference, so far as I know. I'd be more interested in finding source images of some of these stickers/cards to make more faithful reproductions from.

Apologies, my comment was worded poorly. I am sure his work comes from original source images, I just wasn't able to find those images on his site.
