A book “called Polska” found at a bench in my mum’s “blok”

I remember in my family home in Poland in the 1980s and 1990s, there were books on the shelf titled “Polish Almanac.” They contained information about Poland, with an emphasis on folk culture. There was always a section for children with poems and fairy tales. The almanacs were dated and published for each year. I don’t know what year your book is from, but it looks like a pro version of such an almanac.
