Older work of Joyce Clark worth

Her work is all over the web. Are you not facile enough to find it? or are you the artist trying to promote your work?
I find her work kind of "Thomas Kinkadey", not quite competent enough to be considered "great" but sentimental enough to satisfy my Aunt Mary.

Her works are priced between 3 and 9000$ , and for the loife of me, I dont know why. She does mostly oils of landscapes and she only wishes she could be considered a California plein aire artist.

Hi, I just inherited a painting similar to what you described. Did you ever find an answer to this post? Thanks for any help!
