No, no, no, you've got it all wrong - it's 17 Wacky Packages Boxes series.
Oh... good. Because I don't have time for a Wacky mystery at the moment. I remember some rumors early on of 17th series, 4th Series white-backs, 15th tans, full shipping cases of each series from 1 to 16 sitting in a warehouse. All kinds of treasure hunts. Although... the one that was true, but I don't know if anyone ever collected them all were the "GLOSSY" stickers. Seemed like 5th would be the easiest to assemble, but I think I remember 3-6 having glossy variation fronts. Never saw a glossy BUM & Choke, though. And someone was after collecting double sets of everything, one for single and one for double asterisks...
I can't imagine how hard it would be to find a PSA 10 run of all possible 3rd series sets - tanback, whiteback, glossy of each, and single and double asteristks of each, all with Spit & Span variations... no wonderbread, 1979 or English allowed. There's an 8-set challenge for the complete-ists out there!
