What's the deal with these Mongoose decal sets? I've found them at several different old bike shops, but don't recall ever seeing a Mongoose bike with stickers like this.

it came from the 90's

Gary Debacker, Shelby James, Tavis Chipres era?

aftermarket. came from a company called "stick-em-up" who, at the time, made all sorts of decals. some officially for the bike company, some not so officially.

Thanks Mr. Coasterbarke, thats what I figured. Especially since they aren't stamped "BMX Products" anywhere...

This style of sticker went on Mongoose's 1985 Mountain Bikes
