Hello. This is the first time I'm posting here and I hope you can help me. I've grown obsessed with this typeface and want to use it for a personal project, but I don't know its name. It was used in the 1950's for the Continental Hilton hotel in Mexico City. Sadly, the hotel doesn't exist anymore since it was destroyed in 1985 and few pictures remain today. The attached file is the best quality I could find. Hopefully somebody recognizes it and finally solves this mystery for me. Thanks in advance!
