metal messenger logos

my friend Jimmy who works as a bike messenger (and who is also the author of a widely read story about bike theft in downtown L.A.) recently got a very light bike frame he wanted to decorate with a metal band inspired sign reading "messenger".  here are a few proposals i came up with. they are all symmetric.  i'm particularly fond of the inky-drippy one i colored to resemble an old xeroxcopy-like old school black metal album cover.
