The Franz Mayer collection features extraordinary pieces made of precious metals and glass, as well as watches, Mexican blankets and shawls, crafts made of paper, straw and multicoloured feathers, maps, bells, locks, fans and hundreds of household items. The large array of European paintings from the 15th to the 20th centuries, and of Mexican paintings from the 16th century on would, on their own, make for an impressive collection. Over 7,000 volumes on topics involving applied arts comprise the contents of its ample and comfortable library.
