I'm Not Bobby

This is a chainwheel tattoo website that my friend George turned me onto. Most of these designs are dated from the early-mid 20th century (and some from the late 19th), these are cast iron and also called chainrings or sprockets (I’m sure Moneyfire has more info on this stuff).

Anyway, this website is ostensibly about tattoos based on these designs (also a Moneyfire wheelhouse), but keep scrolling down and they just have a great catalog of all these different models from all over the world.  The creativity in design for these highly functional objects is really neat.
