The only thing in this art that really bothers me is the giant Slinky Dog facade over the switchback area. To my knowledge, that doesn't resemble any box that the toy has ever come in, pre- or post-Toy-Story version. The logo does, but the rest does not. It seems Andy cut this out from a Slinky Dog box, but that's not the box.
My guess is that the real one is too spread out for the size facade they wanted, so they came up with their own design that fits better.
The top of Slinky Dog Spin in the other TSL's is a replica of the real classic box design, which I like much better. In a land geared toward young children, this is a nice touch for some older folks.
