The collection isn’t huge, but the father/son team behind it hits the high points, including Amazon, New York Times, OS X, and iTunes.
Update: One of the Facebook screenshots that the Version Museum is using included Brian Moore’s phone number and other personal information. Per Moore’s general request, I have blurred out that information and I hope the museum does the same. (thx, all)
