There’s Fictional Victorian London; Fictional Flapper London; and I guess Fictional 1900s Kansas (that’s when Wizard of Oz was published)
Also, A Land Without Color is shown to be a Fictional 19th Century Europe. Victor’s commission letter refers to Austria, and is written in German. The Frankenstein novel takes place in Switzerland (a German speaking country at the time), which is likely the same country they were trying to imply they were in.
