Looking for info on my lamp was given to my mother as a gift and when she passed away she left to me. i believe it is approx 90

just curious if anyone can tell me about my lamp. was given to my mother from a friend who said it was her grand mothers. My mom was 68 years old in 1998 and her friend a little bit older when she was given this lamp. i did not see any engavements on this lamp.
