The collection includes thousands of pieces from pre-Hispanic artifacts, religious art from the colonial period, and even modern art by known names, but the majority of the collection is everyday items from the last three centuries. The Casa de Madera has been likened to visiting a grandparents’ attic. There are portraits from the 1920s, barbers’ implements, kitchens and living rooms packed with old furniture and decorations, old toys, watches, telephones, jars, farming implements, musical instruments and more. There is even a pen capable of shooting a 22 caliber bullet from World War II. The owners, Luis Pastor and Ricardo Flores, have been amassing the collection since the 1970s.
