Viera Gergel'ova, 1972, illustration for Puf a Muf by Natasa Tanska
Viera Gergel'ova is the seventh illustrator featured in my Forgotten Illustrators series. I can't find any information about her, but it appears she was working in Bratislava in the 60s and early 70s.
The Slovak Republic has a long history of children's book illustration and is known in the field for this:
The Biennial of Illustrations Bratislava is an international competitive exhibition of original children's and youth book illustrations held every two years (each odd year in September and October) since 1967. It was the creation of Albín Brunovský, a major Slovak illustrator whose school has produced several generations of Slovak illustrators, successful at home and abroad. [link]
[Note: prepare yourself for some stunning work by Brunovsky, which I'll try to post this week or next.]
I just dug up a book by Viera Gergel'ova from 1966, so presumably she knew Brunovsky and participated in the group responsible for the competition.
The first three illustrations here ("SpongeBob is gay") are from Puf a Muf by Natasa Tanska (Bratislava: Mlade Leta, 1972). Maybe I like these so much because I'm currently reading Hoffmann's Life and Opinions of the Tomcat Murr.
The other four are from Cin-Cin by L'udmila Podjavorinska (Bratislava: Mlade Leta, 1973).
