Subastas Retiro, from Spain, sells on 26 April 2017 a "17th century Spanish school" Interior with still life estimated at 1,650 Euro. The description explains that this is a large work (106 by 160 cm) made from 17th century canvas fragments.
All in all: a painting with a rare subject, a mediocre style, and in a terrible condition (which somehow makes it interesting again). No idea whether it truly is Spanish, or what the value might be. Not a lot, probably.
