The cards were real photographs. They were issued in four different sizes. Normal cards were around 62mm x 45mm with some variation due to cutting the photo sheets. Large ones were 70mm x 100mm. There were two special cards, No. 235 (100mm x 140mm) and No. 245 (170mm x 180mm).

A list of cards was given on the back of a special collecting envelope for the series. The large cards are indicated by bold numbers and the two special cards by boxes around the numbers.
