For your delectation we have these nifty postcard books which delve into the wonderful world of tattoo culture.
Printed by Calverts for Duggan Collingwood and Prismatic Pictures each book documents a visual history of tattooing through a series of 22 cards.
You might find a copy or two in Vagabond, our friendly neighbourhood tattoo parlour - the go to place for Hackney cognoscenti and renowned broadcasters to get inked.
Alternatively, trailblazers might want to consider booking a session on Tatoué - the world's first 3-D tattoo machine. Those of a sensitive nature look away now (or don't click that link!).
