This box comes with a paper headed "Filing Suggestions". That is the reason I know its original purpose was for the filing of photographic negatives. It is a handy size though, and could just as well be used for filing recipes, Christmas lists, cards, etc.,etc. It is made of tiger maple and beautifully dovetailed on all four corners. Inside is a sticker which reads, "The Nega File Co., Reg. US Pat Off, Easton Penna." It measures 6 3/4 inches wide, 6 1/4 inches front-to-back, and 6 inches in depth. It is in great condition, considering its age and usage. Only a few minor scratches which add to its character.
