Correspondence between Joe P. Barentine III and Vernon Nikkel. The two began exchanging letters in 2005 and continued until Nikkel’s death in 2010. The correspondence largely covers art in all its various forms -- paintings, sculptures, drawings and fashion. It also covers art collecting, legal aspects of art, art theory and art history. As a volunteer docent at the Modern Art Museum of Fort Worth, Barentine began researching the purchases made using the Benjamin J. Tillar Trust Fund. Among these purchases were Twenty-Five Colored Marilyns by Andy Warhol and Mr. Bellamy by Roy Lichtenstein. Through his research, Barentine discovered that Vernon Nikkel sold these two art pieces to the Modern Art Museum of Fort Worth and reached out to him for background information on the purchase. The two developed a friendship through letter writing and their shared love of art.
