"Win with Wilkie" tin sign

Picked this up today. Appears to be a sign from the Wendell Willkie presidential campaign. Couldn't find anything like it on a quick search. Appears to be original but not sure. It's on thin metal/tin with the sharp corners that are on a lot of the older signs. Anyone ever seen any of these or know a good way to see if it's authentic? I love it regardless just curious about the age of it. It favors an original Virginia cigarettes sign from the 40's that I purchased last week. Thanks in advance!
