Reel to reel warping

Hey, remember the summer? No, not much to write home about, was it? Well I got in my car today for the first time in ages, and look what I found. At some point over the summer, it must have been warm enough to do that to one of my groovey compilation tapes (it's been photograghed while resting on my denim-clad thigh - calm down, ladies). Ain't Mother Nature er-mazing sometimes?

As you can see I don't go in for writing on those little stickers to put on the tape, I love the mystery when you put it in the 'deck'. I wonder what's on it? Probably a weird mix of this, this, this and this.
