     Today, Letterfly is the top producer of high quality airbrushed murals seen on the outsides of luxury motor homes. Wildlife and animal depiction’s provide the mainstay for these works. Also known as Dave Knoderer, since 1975 he has sought sensational challenges in his work. All finished work is commissioned. In addition to paintwork on the exterior of motorhomes, the artist also produces mural work found in homes, oil paintings on canvas, pinstriping and pictorial work on motorcycles and high quality custom paint on all types of vehicals. The artist regularly gives informative and entertaining seminars on Dave Knoderer these subjects and is the instructor of airbrush technique at Ringling School of Art and Design in Sarasota, Florida.

    Starting as an apprentice in the Sign and Design trade his appetite for unusual activities lead him to many sensational projects. A skilled painter, he has designed and painted large wall graphics and theater sets, themed interior and exterior murals in amusement parks and restaurants, crafted delicate Gold Leaf window treatments and the gilding and decoration on Fire Trucks. A true Renaissance man, he has a passion for the Victorian embellishments of an era gone by. This fondness clearly shows up in his "themed" work. What is truly unusual about this artist is that he is equally adept with paint brushes or an airbrush.
