That is pretty cool - There is a street vendor just outside of Jefferson Hospital on 11th street here in Phili that sells these things - and he has a ton of em! My wife was in the hospital for a six week stint a couple of years ago and I would stop by that stand quite often. Some of those old comics got me through some pretty tough times. If you ever get to Phili check it out - you'd love it!
Thanks for putting up the pics -
