I'm looking for info about a particular style of building Esso used. Specifically those with the curved front corner. The building, overhang, sidewalk, and glass were curved with the same radius. An Art Deco metal panel was under the overhang. When was this style used and for how long. Any architectural plans for one of these? I'm interested because it's what my dad's was like and I'm gathering memorabilia from this era. Here is a picture of what I'm talking about. (I spent a lot of time there).

Here are some plans without the curved corner if that helps.

Here are a couple of more.

Thanks. Dimmensions do help.
