8.5"x5.5" , Sharpie Started doing bunches of quick Sharpie things for fun , not finesse (as you can see). Playing around with one of those Sharpie color sets to see what I could get. I got Batgirl , Powergirl in her old Bart Sears suit (my fave) and Aquaman's girl Mera in her classic Silver Age costume. Remember , the one with the bigass flippers? Ha!
