I'm sure the signed Devil's Playhouse print
had measurements of 21.75" x 16" listed previously (same as the TMI one), but it seems to have been removed for some reason. Perhaps those are not the correct measurements, but I'm almost certain it is going to be a large print of that size. All the others have been and they wouldn't be charging that price otherwise.
Each individual poster in the 5-pack
measures 8" x 10".
