Hola,
Well, they seem to love anything having to do with Frogs They're everywhere. Salamanca is a booklovers dream. As a bibliophile, I bought books and I was not disappointed by the quality and variety of titles. The main street, Rua Mayor, leading from one of Spain's most beautiful plaza's, the Plaza Mayor to the Cathedral. The University store has wonderful leather gifts. I bought a satchel that is both functional and beautiful for a very reasonable price.
They have a wonderful shop called Universitates Salamantine Mercatus this is the official gift shop of the University of salamanca, and it has prints, books, leather goods, pens, lovely stationary, etc.

The other shops have lovely posters, ceramics, etc.

Enjoy Salamanca, it is a wonderful city!
