Howdy. I've searched high & low for one of these panels, #AD1. It's been well over a year & no matter what site or who I ask? No one has known anything about them. Looking for a hand up from anyone knowledgeable on these. See if they are actually out there or if someone happened upon a few uncut that were unique yet listed as inserts. 
Only trying to ensure 2 things, to make sure time & effort are worth continuing along with learning what I'm able. Thanks kindly 

These are the salesman samples showing upcoming product. They were given to store owners to entice them to order the upcoming releases. The back would include details about the set and ordering info. 

You are overflowing with info! I catch something new from you on every post, thank you! 

Please correct me if I'm wrong, if given to businesses as a sale or preview sheet/panel .. safe to think they're few & far between? I'd think one might pop up but it'll likely stay fairly elusive.. Like my missing '75 team set mail-in checklist :-)

Yes, I'd say they'd be pretty scarce and hard to come by. It's hard to imagine a time when stores had to be "sold" on the idea to carry baseball/football cards.
