Jan Sierhuis (1928) - echtpaar

Painting by Jan Sierhuis 21-12-1928 / 4-7-2023

Acrylic painting on paper by Jan Sierhuis, bought by my father in the 1970s at the "Stichting Beeldende Kunst" SBK in Amsterdam. Original price 1,300 guilders
Painting 70cm x 45cm, aluminum frame with glass 79.50cm x 57cm
I do not know whether it is a painting or a print; on the back there is the number 8-80. It is unclear whether it is signed.
Condition is good. There is a small 3mm crack at the bottom of the artwork, this has been there since purchase; it has never been taken out of the frame. On the left upper inside there is a speck of paint on the inside of the glass. It was probably still wet when framed.
The glass pane has in the upper right corner a small crack of 2.5cm.

From Wikipedia:
Jan Sierhuis was mainly an expressionist painter, inspired among others by Paul Cézanne, Henri Matisse, van Gogh and Picasso. In his early years he painted naturalistic landscapes. In the fifties and sixties he spent some time almost exclusively working abstract. In the mid-sixties he moved from expressionism to a period mainly featuring human figures. Sierhuis shifted to more figurative themes, such as dancing figures, portraits and landscapes. He spent many summers in Spain. His passion for flamenco influenced many of his works and led him to also work in three dimensions.
