The Ramones one included some guesswork, Johnny, Joey and Dee Dee were fixed in my head but 'the other one' was guesswork. I used the remaining ink for a 'drawing without reference' idea of my own, the Samuel Beckett below. Probably has to rank as the quickest drawing I've done, took about 20 seconds I suppose.
As you can see below I did it on the inside back cover of my sketch pad because it was shiny and would resist the ink. I may do something wild and inky in the near future, these were a lot of fun to do.
