In the 1915 inventory of the Museum für Völkerkunde, the bundle is described as "Photographs of the Exchange Series of Models" "Series of models from the Anthropological Department of the U.S. National Museum intended for exchange. Model of the columned palace of the ruined city of Mitla. Scale 1:18. The framework of the model is made of wood and the decorations are made of plaster. Length of the front of the model: 2.13m (7 feet). Construction costs: approx. 600 US$. The model was not completely finished when the photographer took the picture. Since the original building is well preserved, only small hypothetical additions were necessary to build the model. The platform was created in accordance with the style found on the upper building facades. Length of the original façade: 40.23 metres (132 feet). The model was built under the direction of W.H. Holmes."
