http://www.thetoppsarchives.com/sear...m%20Checklists
Saw a bit on this topic on an old Topps Archive post (see link), so I thought I'd post these photos.
Purchased this on eBay a couple months ago after looking for a few years - an uncut sheet, presumably received through the mail in response to the wrapper offer, of the 1973 blue Topps team checklists.
Pretty rough shape, but for something I had never seen before (and doubted even existed any longer) it was worth the price.
For those of you interested in variations, the checklists on this sheet are all of the single asterisk variety.
