Our attention was drawn this week to the MadameGilflurt Twitter account who posts curious artworks from the 18th century and who had dug up this beauty, titled "The Camera Obscura" by Charles-Amédée-Philippe van Loo.
We got in touch and she used her archive-fu to dig up more for us, none of which we'd seen before, so here they are!
