We’ve seen a lot of great posters and flyers for PechaKucha Nights worldwide over the years — we even created a one-time loop of them for last night’s special pre-Tokyo Design Week edition of PKN in Tokyo — but this latest one for tonight’s (October 29) PKN Oaxaca Vol. 4 may be my favorite so far. Some are “dos,” some are “don’ts,” but which “do” are you?
