This collection consists of 60 cartes de visite, owned by José Antonio Ulloa of Zacatecas, Mexico. Items in the collection include photographs and portraits of European, South American, and Central American royalty and military members from the 19th century.

The cards also contain decorative monograms and illustrations located on the back representing different photographing studios that created the cards.
