Vintage GE Mazda Christmas Tree Lamps

A wonderful collection of vintage Christmas Tree light bulbs. The C-6 light bulbs are circa 1930s-1940s. The bulbs are in a vintage box labeled green, however the fluted matte bulbs are in white (4), blue (2), yellow (2) and red (1). The bulbs are 110-125 volts measuring approximately 2" long. The bulbs are untested, the box no longer has its lid. Nice older holiday decor, a cool relic.
