I stumbled across an old box and inside I found two of our original sticker designs.

We have had variations of the stickers included, meaning the black trapezoid was released in a white version, the purple spot has been made available in several colors, and the "License To Rock" sticker was released in 5-6 colors simultaneously.

There was also a clear sticker, which I believe is the only thing that is not displayed (still, it was just the purple spot with a clear background for windows).  There were also a number of stickers that were hand made by faithful listeners.

I should mention that the purple spot has three iterations, the first with "The Home of Rock and Roll", the second with "Pure Rock" and the current one with Lubbock's Rock Station.
