Einstein Didn't Like Wearing Socks

The boffin didn’t like wearing socks. When he was young he wrote in a letter, “I found out that the big toe always ends up making a hole in a sock. So I stopped wearing socks.”

When he went to the White House to visit President Roosevelt he didn’t wear any socks. Lots of photographs which show his full body feet show this is accurate.

With idle hands and twenty minutes to hand I did this abstract painting with acrylic paint and a small trowel. Can you spot the sock?
