Mixing is one of the best tempera paintings on paper realized by Contempologyc E.M. in 2020. The author expresses herself with her characteristic pink and slight blue shades. Hand-signed on the back. Perfect conditions. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution
