ABSTRACT:
An envelope suitable for photo processing work is formed of front and rear panels connected together to form a pouch. The rear panel has a closure flap which is movable from an upright position to a closed position where it is folded down over the pouch. The front panel has a flap which is movable from an upright position to a position where it is tucked into the pouch to prevent objects from falling from the pouch. The flap on the front panel has an identification tab which is insertable through a slot formed in the rear panel and projects up for convenient access and visibility when the closure flap is in its closed position.
