I have for many years enjoyed viewing Dalhart Windberg's paintings and also Larry Dyke.  They both have galleries that are in Texas.  Dalhart Windberg has a galllery in Georgetown, Texas.  We stopped there on  the way back from Fredericksburg when we visited a  few years ago.  I have seen a few of Larry Dyke's paintings and enjoy viewing them as well.  I did see one of his at the Whistle Pik Gallery in Fredericksburg, Texas and viewed his art online at the Midland Gallery in Midland, Texas.  They are both great artists and work in oil medium.
