This is my Father, 1955 I believe, he wearing his Air Force uniform in the parade, you can just make him out behind the window frame. I think this is a 53 Buick super but it looks like rear wheels have removable panels. the panel are there for the parade but are missing then he is standing in the door. The Skylark had wheel wells that over the wheels, so it is either a special or super but I can not find a photo either of them having movable panels in 53. Can someone enlighten me?
