Found Art in Street

Framed Rothko print (unless it was a well-disguised original) this morning, in quite a decent frame, NW5. Almost quite unbelievable that the person should have thought this please-all piece far too much for their home. Or perhaps they thought that the colours suited the outside on a shitty March morning much better. Which actually makes it - Outside Art. Needless to say, within moment (ie when I went back for it) it had gone - to become Inside Art once more, I presume.
Two days ago I found this:

...on a wall in NW3. It still had canvas board, turps and old tubes of paint and charcoal in it, from 1809. Or something. I don't think they put the word 'Amateur' on art sets anymore. Puts the paying public off.
