Sold For: Login to See Price

Grouping of six vintage souvenir photo postcards documenting staged demonstrations at the Mystery Spot in Santa Cruz, California, a roadside attraction famous for its gravity-defying visual illusions and so-called unexplained phenomena. The postcards show visitors and guides performing classic demonstrations including apparent changes in height, objects appearing suspended or supported at impossible angles, and the “creeping ball” illusion. Each card bears printed captions identifying the Mystery Spot and describing the specific phenomenon being demonstrated. Black-and-white photographic images with period attire suggest early-to-mid 20th century production. All cards show age-appropriate wear, including corner softening, light creases, and surface wear.
