I have a William Trego sketch on Masonite that was given to Baum then Baums son was known to glue the works of Trego varnish and sell them. I found one in the dumpster. Just thought it was a beat up old sketch that was done by a very good artist. Two years later, I find out through museum Raisonne it's an authentic sketch of **5TH CAVALRY CHARGING AT GAINEs MILL, VIRGINIA, 1864** one of Trego's most valuable works. Quite a story. I still have the sketch
