This 500-plus piece 1977 Springbok jigsaw puzzle PZL4085 is Verticalville, the first Springbok puzzle designed and illustrated by Robert Blair (Bob) Martin. It depicts an amusing and very busy comic-strip style cartoon rendition of a self-contained vertical town. Completed size is 18 by 23-1/2 inches.

The puzzle has been worked and is guaranteed complete. The box has one split lid corner, otherwise it's intact and in good condition. Bob Martin's puzzle are so fun and enjoyable to work, virtually every piece holds a surprise or smile in the tiny comical illustrations.
