Here's a drawing I did for a sticker that I just sent off to be printed. Its based off of the following photo I took in high school (96?) of a hot dog stand in Cicero/Berwyn, IL if you were in the Chicagoland area from the mid 60s until a few years ago you probably remember this dude if you drove past it.
These are some initial drawings for a print I'm working on based on tubes used in audio equipment. My plan is to cover all of the tubes used in classic amps from the 50s to the 70s.
