I like that response. The Colder by the Lake Comedy Theatre is definitely a part of the city's cultural history, so his legacy is very much still in Duluth. And you are almost certainly correct about his identity. According to the obituary of Lawrence Whalen -- or Uncle Larry as he liked to be called (and French Larry too) -- he had strong connections to Madeline Island his whole life and was very actively involved in local affairs, which would explain specifically why the poster is on the wall in a café in nearby Washburn.
