Looks Slingerland-ish, based on the purfling and the peghead, but they aren't definitve. Could be Oscar Schmidt. Doesn't look like Lange to me, and it's not Kay. Wizard was a trademark of the Western Auto stores (Remember them?), which sold such an eclectic mix of products that banjos could have been among them--or not.
Heck yea I remember Western Auto Stores! My dad owned one the whole time I was growing up in Osceola, Iowa. The Wizard label was used on some items, like appliances and some small stuff but I don't think I ever saw a Western Auto trade label like Wizard, Truetone, Revelation, etc used on musical instruments. But who knows what they labeled banjo's in the 1920's. I can only remember the 1960's-80's. Everything before and after that period is a bit cloudy these days.
