Linoleum cut block
A printing device, it is constructed of battleship linoleum glued to a block of wood and made type-high so it can be cut into with special tools. Linoleum is desirable because it is soft and easily carved in relief and durable for many copies. To make a print, the block is inked with a brayer and printed like a woodcut method either by hand or with a press. Source: Ralph Mayer, "A Dictionary of Art Terms and Techniques"
