Crate labels were pasted onto wooden crates in order to identify the contents and origin. Brilliant colors were used to attract consumers at the local markets. Today, pre-printed cardboard boxes are used instead. Yes, labels are easy and inexpensive to frame. Most crate labels have a large border, which allows you to mat the label with ease.
Chain stores sell nice oak frames for a reasonable price with glass and mat included.
The abrupt change to pre-printed cardboard boxes for packing fruit resulted in a surplus of unused labels. They were forgotten and abandoned in packing sheds, fruit grower's collections, and printer's files. Over many years and with much research, collectors have gathered the labels that still exist today. We only buy and sell vintage, original labels. Because the labels we sell were never used, they are in perfect condition.
