This is an old letteropener advertising The Humphrey Inverted which appears to be some type of light bulb or lighting device. It is an interesting device and the same picture of it is shown on both sides of the flat piece of celluloid.
It measures about 7 3/4" long and is in fairly good condition with very light scratches on the picture. The very tip of the letter opener looks as though someone bit it.
The pictures are not shown at actual size. Please refer to the description for actual measurements.
