No, this is not Art Deco, but I’m posting it because Mayan architecture was a major influence to Art Deco. There are examples of “Mayan” movie theaters, office buildings, public buildings, etc. This is an example of the original form and looking at it, you can see how it could easily, with only a few changes, be interpreted into Art Deco.

BTW, if you’re interested in other photos or links related to forms of architecture that influenced Deco, “like” this photo and I’ll take it as a hint to find more.
