Hey all, today as I was touring a private collection known as Collection 21 in Erlanger, KY I came across these two beauties. Wasn't allowed to touch the cars and couldn't get pics of the data plates. You'll forgive me for not knowing if the cars are later 56s or 57s. That's part of why I'm here, to learn! Maybe they're known to the group? If I got back I'll try to snap pics of the data plates.
