The Masters Trash Bin

I appreciate all drawing, especially studies & sketches, experiments, the informal, personal-private, and even the haphazard, duds, fails, DUIs, etc.  For more insight into an artist, their their how and why, where and when, or even 'who' they were, etc., take a close look at their drawings, such that they exist.  Consider any extensive portfolio of drawings to be the ultimate self portrait, a tell-all, a log, etc.  And, as such, you'll see their handy works weren't all home runs!  This is a selection, imho, of such 'less-than-perfect', "my-materials-went-awry!", 'special in their own way'... type efforts, or even pages that could well have been pinched from the trash(!) -an ongoing but incomplete collection just for fun, presented in no particular order (to include but still missing some major names). 

Parmigianino was a one-of-a-kind master, always amusing and somewhat goofy, mischievous, -probably fun to hang out with. He liked magic & alchemy and died young at 37. The liberties he took in his work are still astounding 500 years later.
