This week, we present a tribute to one of the titans of the Golden Age of Radio - William Conrad.  First, Conrad stars in his signature role of Matt Dillon, US Marshal on Gunsmoke.  We'll hear "The Photographer," originally aired on CBS on May 5, 1956.  Then, he fills in for an absent Gerald Mohr on The Adventures of Philip Marlowe in "The Anniversary Gift," originally aired on CBS on April 11, 1950.
