Here is a real-photo card of a woman wearing a traditional Czech costume. The picture dates from sometime between 1930 and 1950.
These next two appear to be from Uherské Hradiště, a center of Moravian Slovakia located in the Czech Republic near the border with Slovakia.
Both of these photos have interesting studio props. There are tassels on the furniture in the first one, but also on the chair in the second photo. The clock plant stand is also an unusual addition. The second photo appears to be a wedding portrait. Both photos have pushpin holes indicating that they were pinned up somewhere to be viewed as treasured memories.
Here are the backs of the cards in the same order. The last two cards have writing on the back. Alas, I don't speak Czech or Slovak, but I think the first one says Sister Marika and Franta's wife and the second one says something about my wife and I. If you can read this, feel free to correct.
