A butter stamp or butter print[1] is a device for stamping or shaping a design onto a block of warm butter.[2]
Butter stamps were sometimes commercial but usually purely decorative and applied in homes.[3] They were typically made of wood and feature simple designs of cows, flowers or geometric patterns and, if commercial, the name of the retailer.[4]
Often, they formed part of a box-like mould for forming the whole block. Other designs achieved the same effect by carving the design at the bottom of a butter mould.[5] Part of the intent for commercial moulds and stamps was to demonstrate consistency in the quantity of butter sold.
