Tiny wood engraving print by Bewick from late 1700s-early 1800s. He engraved his own finger print at life size into this scene, the whole thing is about 4x2cm.
There is a detailed cottage on the right with a little fence, a rider on a horse is half visible with the front half under the carved fingerprint, there are trees behind. It is a black ink print on white paper, reproduced at the original scale in a book called Thomas Bewick, Tale-Pieces.
