Among the things I enjoyed when on sabbatical at Stanford were the really cool exhibitions at SFO. Among other things, this included one of classic boardgames.
Harry McCracken also posted pictures of several other typewriters from the exhibit on his Twitter feed. Take a look at this one, this one, this one, this one, and this one. This should be all of the typewriter pictures that he posted as part of this thread.
