Not my usual cup of tea

I rarely pick up these type of 10 speed bikes but got this one at a good price and found the Schwinn graphic on it unusual
Never seen this diamond shape stencil before on the bottom tube thought it might be something special ? The frame is a smaller size 26" wheel , Purdy clean, probably just flip it ?

Looks like a circa 1981 Varsity.

That is pretty unique. Never seen that style lettering outline before either.
