For much of its run, Lawman was sponsored by R.J. Reynolds that made Camel Cigarettes. Because the obligation to do so was written into their contacts with Warner Brothers, John Russell and Peter Brown did both print and tv advertising in character for Camels. After Laredo, Peter later did print ads for Old Gold Cigarettes. A sad footnote is that John Russell died a very painful death from emphysema in 1991, about the time Peter Brown finally kicked the habit. Peter's Laredo costar Neville Brand also died of emphysema in 1992.
