Now that Ancestry has added many school year books; one of my first searches for Guse turned up a very nice picture of Rex Guse, your grandfather. It's 1926 Univ.of Nebraska, picture of the Lutheran Club of which Rex Guse was VP that year. Posing for school publications was serious business in those days; or maybe it was just the Lutheran Club.
Drop me a line if you can't find it; I'll snag a copy for you, Paul. Cheers, Clayclay@foxcats.com
