The drawing below is from Gustave Eiffel's book describing the tower that bears his name. There are 53 of them in total.
XXX. Anglo-American Bar and Theater
Another interesting board for anyone interested in the history of the Eiffel Tower. It shows the theater on the first floor, as well as the Anglo-American bar. The theater, as indicated, was during the World Fair of 1889 a Flemish restaurant. This technical plate is closer to the previous one, which describes the two French and Russian restaurants.
