Period authenticity

I saw the Key Tower (built 1991) in at least one scene. I also saw a large non-Cleveland skyscraper in several other scenes. Whereever they filmed the movie (it was not mostly in Cleveland I think), they accidentily included a large skyscraper that was clearly not there in the 60's-70's and even today.

There's a walk signal in one scene that had me wondering -- I don't really know-- if they were using the orange-hand/white-figure, rather than the words Walk/Dont Walk in the 70's.
