lot of 45 vintage commercial 35mm photo slides of Tangier, Gibraltar, Granada - the Alhambra

Lot of about 45, vintage 35 mm photo slides of Tangiers, Gibraltar and the Alhambra ("The Red Fortress") the home and castle of the king of Islamic Granada prior to the Spanish conquest in 1492. About half of theses slides are commercially produced and are labeled for "Tanger", "Gibraltar" and "Granada - Alhambra" The rest are home shot and and seem to be southern Spain and/or North Africa (lots of Islamic architecture and arid landscapes). A number of them are hand labeled for Morocco, Tangiers etc. We're not sure of the exact vintage, but the home slides look to be marked 1980.
