I purchased these on my last Italian buying trip to Sorrento, Italy. These were found in a lovely antique store in Sorrento. Fell in love with the colors and subject. Each of the 5 tiles is 2.75" by 2.75". They features starfish, anchor and seahorses. They have a faint mark on the back that looks like IA but not sure. These are Italian majolica, a traditional style of hand painted tin glazed earthenware. Cobalt blue and white coastal design particularly from the Amalfi coast. Loved finding these for you! Condition overall is good. Typical minor nicks on edges on one seahorse and one anchor. See images up close.
