Bob's primary medium over the years was oil paint. Two of my previous postings featured some of his work. "Railroad Art" was posted on July 18, 2010 and it featured a large painting of Union Station in Kansas City. The same posting also featured a painting depicting a classic diesel 'stream liner' passenger train coming down the tracks. The first painting is in the private collection of a art & antique dealer in Kansas City but the whereabouts of the second painting is unknown.
My second posting of Bob's works was back on September 18, 2010. It was entitled "Ships From the Past" and it included a pencil drawing of the tugboat 'Goliath' as it guided a tramp steamer into port. That drawing is part of my collection of family artworks. Also posted on the same blog was an oil painting of the 'William S. Mitchell", a Corp of Engineers side-wheel paddle boat, also know as the death dredge. That painting is also part of the antique/art dealers collection in Kansas City.
As for these four drawings, the first and third are in my collection and my son has the second and fourth sketches in his collection.
