Photo of Flap Envelope

Subject

Block family
Glass negatives
Photography -- Negatives.

Description

Glass plates that are not enclosed are in danger of being scratched or
having the emulsion pulled away from the glass, and portions of the image being lost. Four flap
envelopes are the preferred enclosure method for glass plate negatives. These envelopes completely
enclose the plates and can be opened without the plates rubbing against the enclosure.
