This is a very useful old enamelware piece - an extra large refrigerator drawer.  It has usage wear but very usable for storage or display.  It has a metal lip that was used to pull it out - your fingers fit under the lip to pull the drawer out.  It has two vent holes on each side.  It has some wear, but none have worn through the drawer.  Please see photos - you can see spots where the enamel has been dinged, but no holes have worn through.  I used it to store photos.
