Kurt, not only is it huge, it hangs my Preview app. This pdf is way too big. It's high res scans of a book. For archive purposes, that's fine, but it's a beast to open.
Pages 3 and 4 seem to be blank. I don't know if they are missing or if I got a bad download.
Before you open this, turn off the page drawer feature in your reader and just open one page at a time in order.
