Vintage Sylvania Blue Dot Flashcubes — a box of 3 flashcubes (12 flashes total), for use with standard flashcube cameras. Made by GTE Sylvania Incorporated, Dyersburg, Tennessee, USA.
The box shows notable wear typical of its age: torn/split corners, edge separation, and surface creasing (see photos — box condition is part of the listing). The included exposure guide chart and safety/caution info are printed on the reverse and are still legible. Three cubes are present and appear intact.
Sold as-is, exactly as pictured. As always with vintage flashbulb items, sold for collectible/display purposes — untested and not guaranteed to fire, given the age of the flashbulbs.
Condition: Vintage/Used — heavier box wear (torn corners) contents are complete.
