Good morning! Huber is considered a very good 20th century artist but is currently unlisted and only a few of her works have ever entered the public market--at present, a work of that size would typically retail on the secondary art market for under $300.
Richard K. Collopy, likewise, it known but unlisted and honestly trends closer to décor grade art rather than fine arts--there are several of his works in open guides, but none have ever sold openly for over $110 to date.
Of the two, the Huber would be the better investment long term, honestly.
