As part of its 80th Anniversary celebration, TMR has issued two sets of 7 CSP’s. The first version is numbered, the second set is un-numbered. The numbered CSP’s share the same design as the un-numbered, but have a number ghosted in the design. To the best of my knowledge, no “sets” of the same numbers were sold.
The first design is for Camp Aquehonga. It features the Indian Cliffs “chief” alongside the waterslide.
The numbered version is designated the AQU2007X1, the un-numbered the AQU2007X2
