For my 200th post, I give you a Leonardo

Charterhouse Auctioneers, from Dorset, sells on 21 May 2015 a "Continental School" portrait of a lady, estimated at £200 to £300.

It seems more logical to call it "School of Leonardo", as it is clearly influenced by his works. I would call it a variation on La Scapigliata. It should be worth a lot more than the estimate, as Da Vinci is still very popular and some people may speculate on who painted this (it isn't worse than many things that get very speculatively given as "by" Leonardo sometimes). UPDATE: not sold, I'm really doing great on these jubilee posts :-D
