|The Stanley Gibbons catalogue states that this image is a Caxton woodcut. However, there is, in fact, no woodcut of this image in Caxton's The Game and Playe of Chesse. This stamp is similar to the Caxton rook - but it is not the same. |
The German GSM catalogue states that the image is from the chess book of Jacobus de Cessolis. To my understanding, the latter does not, in fact, exist as a 'book', but rather as a number of different manuscripts transcribed manually by different monks / scribes over the years. It is possible that this image is from an illustrated 15th C Bohemian translation of the text of Jacobus de Cessolis that is held in Prague. ?
