Two paintings with E.G.Co. Line No. 704A Frame No. 224W Order No. 1620 Subjects are Katrina & Adrian. Would like to know how old they might be.

Do the images look like this?

I found some information on the original artist here:
Anne A. Farrell - Obituaries
It seems like she did most of her work in the 1940's....(why is my font blue???)
