It could be, but try and remain objective. Honestly, one of my schoolmates had a tumblr years and years ago that were only "trippy pizza" pic/gif related; and it was only because she really liked eating pizza. Pizza pentagram photos are everywhere, and prior to PG, I would have been like, "haha, neat!". As would other unknowing folks. So, if you find a lead, great. But I am not convinced on that alone.

Looks similar to imagery at 5 points pizza in denver.
