The head of a creepy man smiles at us, seeing the ages that have gone by since he was created. The original artist, long and gone, this work lives on. The original ad proudly proclaimed: "Every body and his big grandmother are going to buy their valentines at cupid's original head quarters, J. Shillington's Odeon building" I wonder where the small grandmothers got their cupid stuff.
