|Aquanauts Minifigure Pocket Clip|
The rare Aquanauts Minifigure Pocket Clip was a Patch & Pin themed item released in 1992. This set was released three years before Aquazone sets were. It is nearly identical to the then upcoming Aquanauts minifigures, with the exception of the arm colour. Because of its colouring, this would leave us to assume that this was a precursor or prototype of what would then be known as Aquazone.
