Collection of souvenirs and ephemera from various Macworld Expo events, highlighted by the Apple Pro Mouse introduced and given away at Macworld New York 2000, used but in its original box. At the end of Steve Jobs's keynote address, he informed the audience that taped under each seat was a ticket redeemable for Apple's first optical mouse—'I want all of you to be the first ones to get your hands on it,' said Jobs. Additional items include: programs from the Macworld Conference & Expo events held in 2001, 2002, 2003, and 2004; souvenirs including a tote bag, notepad, and pins; nine t-shirts; and four 24 x 36 Macworld 2000 "Yin/Yang" iMac posters. In overall very good to fine condition.
