Painting, pastel (Voldemar Kallis, Riga)

[Amateur]

Presumably the author of your work is a Latvian artist Schoenberg Georg Yanovich (Georgs Šēnbergs 1915 - 1989). Sometimes his name was written and how Shenberg, Schönberg. The latter name seems to me - the true (and Šēnbergs - latvinizirovannaya), for the second sign of the signature is similar to the combination "ch", written by the so-called kurrentshriftom (gothic cursive) and the third - more like an "o" than "ē". Apparently, he was the Baltic Germans, because in 1944 he was drafted into the German army. Most likely, you - his early work, in adulthood his style of painting changed.

I managed to find only his signature later - at work in 1952 (see 1, above right). It's not like in your work (the letter "Š", however, is similar), but there are More and monogram (lower left), the second letter which is very similar to the beginning of the names to the signature on your picture. In addition, the monogram on his drawings (see 2 and 3) show a very characteristic writing of the letters "G" and "Š" - the same as in your work. Such writing capital letters "G" I met only by Schoenberg.
