Farm Publication Comics: Gramps and Hired Hand Harley

Here's another one of those comic strips that ran in farm publications. This one is by the team of Madsen and Entwhistle. I have no idea who these guys are, but the art and gags are pleasant enough. The strip ran at least 1947 through 1952, and perhaps much longer. My samples are from the snappily named Wisconsin Agriculturist & Farmer, but it may have been appearing in other farm papers as well.

Can anyone contribute more information on this strip or its creators?
