Celia Gimenez's oil painting "Las Bodegas de Borja" ("Borja's Wine Cellar"), was fetching
euro620 ($808) Thursday, doubling its starting price after 31 bids. The sale closes Monday.
Gimenez became a sensation in August when pictures spread on the Internet of an "Ecce Homo" ("Behold the Man") mural in a chapel in the town of Borja that she disfigured while trying to restore it. Twitter users redubbed it "Ecce Mono" ("Behold the Monkey").
The painting has since become a tourist attraction and the image has been used on T-shirts and wine labels.
A note on eBay says the auction's proceeds will go to the Catholic charity organization Caritas.
