I figured these would make great trade bait, as I didn't collect them. I've not traded any, but I have given away several thousand of these inserts and promotional cards.
I pretty much classify most of them as fantasy art.
I had a lot of these complete sets too, some of which I still have a few sets.
I really have no idea of why Campbell's would put out a card set, but hey why not Hershey's did too.
I'll leave off here, and do another row of scans some time or another.
