Henry Moore's shelter drawings are for me some of his greatest drawings. During WW11 when the aerial Blitz of London took place people took to the underground stations and tunnels for protection from the nightly bombing. Moore brought all his knowledge of art history to record the use of these temporary shelters. Returning to his studio to work up his quick drawings. I was lucking as a young artist to see a substantial body of The Shelter Drawings in an Exhibition in London. The technique in the drawings was dazzling. I learnt from his extensive use of white wax crayon, that it repelled the ink washes and watercolour he had applied. The figures emerging at times spectral from the surrounding darkness. I always feel if you want to learn drawing, learn from the best. I have made loads of mistakes over the years in my work, but see it as a learning process. Moore's drawings are still as relevant today as they were then.
