If you are fortunate enough to be in Madrid this spring, do go and visit the M.C.Escher exhibition. The venue, Gaviria Palace, I have read and seen, is absolutely amazing.
The official website is: http://eschermadrid.com/
A banker’s palace built in the mid 1800s, in the ornate Italian renaissance style. Photos of the interior abound on Facebook, Twitter and Instagram.
One of my prints, Fifi at the Salon is part of the exhibition. I am excited at this prospect.
