My Rattle & Hum "Edge" Shirt

Some background on this one...I first discovered U2 in 1994. First found out about Rattle & Hum when I was laid up with a hip injury and watching TV on St. Patrick's Day it came on VH1.  This shirt is one that my Dad purchased when he was on a work trip in Panama back in the early 80s. I've always loved that shirt...way before I knew it was one just like Edge's. Needless to say after I saw the movie I demanded the shirt from my Dad. He was happy to give it to me since at the time he was using it to work on the cars in the garage!

I'd love to know where The Edge got his...
