Last year I made a series of drawings to try out new shapes and these dish-looking things started coming out. In December I made a couple of paintings on scrap ends of MDF board and people seemed to like them. I did, too, so I made a few more.
They're all oil on 1cm (excluding the third one,which is on .5) thick MDF, roughly 23cm by 19cm, securely wired on the back for immediate hanging, and inexpensive.
