Again, these are pictures that are not going to make my official 'show', for various reasons:
Girona - view from old city walls:
Optical illusion painting, from the Dali museum, Figueres:
Room in Alcazar, Segovia:
Roman mosaic, Empuries:
I have the official show down to about 200 slides. Had to cut out many that I wish I could have included, but I don't want the audience to revolt.
