The picture shows an inside and outside view of this Old Empire Room Chicago Advertising Souvenir Photograph Folder. The folder is not dated but it is old. These types of photos are taken of customers and then sold to them as souvenirs before they leave. This folder is signed by five of the people in the photo. It is marked on the two sides as follows:
THE EMPIRE ROOM AT THE PALMERHOUSE CHICAGO A HILTON HOTEL NO. 7063 A
To judge the size the closed folder measures 8-1/2'' x 7''. The folder and photo are in excellent condition as pictured.
