CIrca historical concepts

Can you add the historical promptings such as  1920's or 19th Century or somehting like that to get aomething in that era or other eras. Everything I try gets me modern images, when I want something from the past or distant past. Or you can give examples on how to get something like that. 

Also, AI needs to be taught human anatomy better. I am tired of getting images with 6 or seven fingers or legs, or feet coming out of the body in a completely skewed or distorted manner. Thank you.
