SPX was a comic book festival that went on the same day as our trip to Philadelphia. A buddy of mine went and picked up some zines and books, one of them by one of my favorite comic artists, Michaela Colette.
Her books are all hand printed and they're really fun to both look at and touch.
Read 'Bullshit Frank and Gorilla Joe' if you ever get the chance...i-it's funny and super satisfying.
