Bossman seems like an odd choice but the other 2 are pretty cool.
Bossman had a cake mold too but you're right, especially given the time period, he seems like an odd choice. By late 1991 he was on the down part of his career with a feud with IRS, a 8 man tag at Wrestlemania with guys who had nothing else going on and he had time off from the Nailz injury and once the Nailz fued was done he was left with nothing. Bret would have been a good choice for party items as he had been IC champ for a long time and HW champ at the time. Hogan hadn't even been back long and he got a full page of merchandise in the catalogs. I think he and Macho even had pages before Bret.
