A big thank you to VonMurr for sending the first ten covers in this post. They come from his personal collection.
The rest were found on my searches through online Polish bookstores.
See my first two posts of Polish book covers: 1 and 2.

Apologies for the scrappiness of the images below this point. Clicking will not reveal much larger views. (I didn’t disable the click-through in case someone wants to “favorite” an image on flickr.)
