I've always wanted to visit Cuba, and hope to do so before it changes too drastically. I imagine it to look similar to this 1949 postcard, though I'm sure there aren's so many commercial signs. The cars may look similar though, since Cuba still has many vintage cars in working condition. The Saratoga Hotel, dating back to 1879, is still open for business and looks like an elegant place to stay.
Here's another card that shows an earlier view, but the postcard itself wasn't sent until 1954. Note that the card was published by the Roberts Tobacco Co. of Havana. I like how the Asturiano Club Building extends into the white border of the postcard.
Here are the backs of the cards in the same order.
