So I thought this was an interesting and rather odd bit of toy history. From the source:
“Pictured above are the two covers of an insert that was included with some G.I.Joe vehicles and playsets sold in late 1990 and 1991. One side featured mail-in offers for one of Hasbro’s toylines, G.I.Joe. The other side featured mail-in offers for another Hasbro toyline, My Little Pony.”
