These are cards produced by Monty Gum, from Leiden, the Netherlands. Each set had 64 cards, each 7 x 5 cm. There were two editions, although the photos were identical:
The first 15 cards were all portrait, the rest all landscape. Most are publicity images, plus 3 "film strip" cards (1, 4 and 12). Two images are used twice, with different cropping (50 and 55, and 25 and 47)
