Uncommon vintage 8x10-inch black and white publicity portrait of the football star-turned-actor as he appeared on T.V.'s "Father Murphy" (1981-1983), boldly signed in black marker in the 1980s. In good condition, with a minor diagonal crease to the lower right-hand corner. Olsen was also memorable as Jonathan Garvey on "Little House on the Prairie" (1977-1981), a character created after the death of Victor French to serve as Charles Ingalls' new sidekick.
