Two entirely unrelated pictures apart from the fact that they both come from the same collection of Dutch cards dating from around the time of World War II.
The first, from 1934, is one of a series showing the story of Cinderella, possibly one of the most well known tales around the world, with one of the variations dating back as far as 1 BC. There are Ancient Greek versions, Roman, Chinese, and several versions appear in the Arabian Nights.
All or most of the tales seem to involve a hard-working young girl being being freed from oppression by an amazing event usually involving the loss of a slipper. The slipper is of course found by a prince who searches for the girl and they end up marrying and no doubt live happy ever after.
The stories have been studied for many years, resulting in such works as "Cinderella: Three Hundred and Forty-Five Variants of Cinderella, Catskin and, Cap o'Rushes, Abstracted and Tabulated with a Discussion of Medieval Analogues and Notes". I'm sure it makes good bedtime reading.
To change the subject almost but not quite completely, the girls in the next picture don't look at all oppressed and are most likely princesses in someone's eyes. I should put that in the past tense because the card dates from 1934.
Although much later than the picture of Infanta Beatriz of Spain shown in this week's Sepia Saturday, there is quite a similarity in the way the girls are dressed, white dresses with shoes and white socks. Even more recently than that, I recall being forced into something similar myself when I was still too young to protest. Modern little girls don't know how lucky they are.
