labelbacks
A labelback is a type of postage stamp that features a design or image on its gummed side, the side intended to be moistened and adhered to an envelope. This contrasts with standard stamps, where the back is typically plain or contains only a watermark or adhesive pattern. Labelbacks are less common than traditional stamps and were primarily produced in the early to mid-20th century. They served as a decorative or informational element, sometimes depicting national symbols, historical figures, or advertising. The use of labelbacks was not widespread and they were often found in specific countries or as part of limited print runs. Collectors sometimes seek out labelbacks due to their unique nature and the historical context they represent. The production of labelbacks was a brief experiment in stamp design and has largely been discontinued in modern postal systems.
