Vintage painting "Virgin Mary of Mathematics", England, 1970s

I bought this amazing, exceptional symbolist/surrealist work from the 70s in London about 20 years ago. This "Mathematical Virgin Mary" is quite mesmerizing. Magazine cutouts, cardboard, gouache paint, and these handwritten mathematical formulas that cover the frame are incredible. The creative mind behind this work spent many hours achieving it. Very good condition with some signs of age. The box dimensions are: h: 32 cm w: 45 cm d: 10 cm.
