Old 1920s or 1930s vintage machine age industrial portable metal card catalog for organizing and storing photographs, postcards and other keepsakes. It has industrial olive drab paint and locks with a small key. It would even work for storing a coin collection!
This old card catalog still has the original label decal from Art Metal of Jamestown, NY. It measures about 16" long (front to back), 11.5" wide (side to side) and 6" deep (top to bottom).
