For those who like looking at classic cars, they've got some nice old photos of those and old Wisconsin highway photos in the 75th Anniversary video they recently released: YouTube link (http://youtu.be/FCqzML0ujso?list=UUY_n4vHYIE9AHr6DAFJ_IbQ). At 2:47, they have an old shot of a US 12/Wis 13/Wis 23 multiplex sign.
