Hi, You can find more info on Harriet Spleth Bellows on website Smithsonian American Art Museum and renwick gallery. On this site search Harriet Spleth and you can then find out more. She has an art degree and born in 1946 in Pa. She gave up art for a long time and was fascinated by flying going back to art in 1997. Bellows might be her married name. From this site I get the picture her art is expensive and some of her work is in the Smithsonian
