I do not know. I obtained these items in a box from an auction but I have no idea what they are. They picture images of buildings/street from early to mid 20th century, as it seems. Each set of 3 have the same image. In the back some say blue, others red or black (as per pictures attached). One of the images has an entrance and a logo for the Red Lion Hotel in Salisbury (I believe) and the other is a view of some street with a garage sign but can’t identify any more details.

Each player is 15x9 cm
