I am reading 'The Russian Experiment in Art. 1863-1922' by Camilla Gray. Slanted crossing lines was one of the hallmarks, a discovery of the avant-garde.
With this photo of my cat Milka with kittens I pay tribute to that wonderful period.
(By the way, one kitten, all black with a sliver of silver white on the back of her neck, is still up for adoption. Lively character, good for witchcraft.)
