Tex Dawson, Gun-Slinger no.1 from Jan. 1973.
Yet another of the reprint titles that flooded the American comic book market in the early '70s. As far as I can find out this was the only issue and reprinted 1950's cowboy stories by John Romita, George Tuska and Al Williamson.
A very minor footnote in Marvel's history but a lovely cover by Mr. S.
Soundtrack: Here Comes The Sun by The Beatles. ( I don't think so: just more snow! )
