Crepax does a great job of using color and panel borders to convey the difference between reality (in black and white) and fantasy (in color). The transition between the first and the third panels work really well and this is one of the few times that I’ve seen the stacked first and second panels work – it’s clear what order the panels are meant to be read in.
