Thanks you for posting this. You know there was a book store a few doors down from Comet Pizza it was called Lambda Rising.

I believe it may have been the first openly gay bookstore in Washington DC.

Anyways, it has since closed and a new book store has taken its place. Politics something or rather.

I found a few articles and clippings online.

Notice in the final link, advertising Lambda's hours, there's a butterfly symbol present. Pedophile symbology perhaps.
