A rather unimpressive collection with the exception of the IBM and NeXT logos. In particular I always hated that OS/2 logo--so boring and now I know who to blame. The Westinghouse one actually ages pretty well.
There are some fun surprises in there. For example, I didn't know Rand designed the logo for Columbus, Indiana, a small town I used to live by. The C's from the logo are sprinkled in art and signs throughout downtown.
