I dunno, perhaps, perhaps, just perhaps this poster might have been an inspiration for Winsor McCay to dream up Little Nemo in Slumberland—coming out several years before Nemo's debut. Y'know, Nemo's dream friend Flip was a sort of a clown . . .
Well, anyway, this is a fun approach for a circus promotion, although the graphic layout could have been done a wee bit better by not spreading all the characters out so evenly.
