8525 Scuba Diving

Mattel’s Mark Strong Scuba Diving Outfit, reference 8525, was released in Europe in 1972 as part of the original Mark Strong range that preceded Big Jim. Designed for underwater adventures, this vintage outfit transforms Mark Strong into a scuba diver ready to explore the aquatic world, reflecting the sports and adventure themes that defined Mattel’s early action figure line. The documented clothing for reference 8525 includes a black scuba-style jacket and matching shorts, creating the distinctive appearance of a 1970s diver. Issued during the short-lived Mark Strong period, the set illustrates the close connection between this European character and the emerging Big Jim collection. Its specialized diving theme also distinguishes reference 8525 from the more conventional sporting outfits released alongside it in 1972.
