The beehive panel paintings are unique Slovenian form of folk-art, with wide-ranging figurative motifs and images, religious and secular. The classical period of the beehive panels was from 1820 to 1880; sadly this art form ceased existing by 1918. Over 600 motifs have been discovered so far. The largest exhibit of beehive panels is located at the Museum of Apiculture in Radovljica, Northern Slovenia.
I haven't seen these in 'real life' as we haven't been in the region, but they seem quite amazing! I did purchase some fine honey products at Ljubljana market though :)))
