While I was looking for the pinup, I noticed his known body of works exceeds 400.
The 19th century painter Bouguereau had at least 822. Even current day hacks who fob stuff off as art don’t necessarily approach that number.

I love the Grecos lining the entrance hall of the Prado. It’s religious, ethereal.
