I have a radio that my grandmother gave me, which she had gotten from her uncle. It's a Polish radio from the late 1950s or early 1960s. My Polish friend Rafal at work has identified it as a Diora Calypso; I couldn't really read the company name on the right of the dial.
I've taken two pictures of the radio.
The first is the whole radio, from the front.
The second is a close-up of the radio's dial, so you can see the cities listed. I particularly like that the Polish cities have a little cross-hatch in the bar next to their names, for easy identification.
I got e-mail from someone in Poland who tells me that the radio started production in 1959, and that it was the first Polish set to fully receive FM. Neat!
Really! Want proof?
