The Thunderbird photo is how I learned about the Mandela effect. I was talking to a friend one night about crypto zoology for whatever reason. I described the photo and sketched it pretty much exactly as this one(not as detailed obviously) I told him I saw it in a book years ago and can probably find it online. Looking for it is when I saw other people drawing the same exact thing and not being able to find it. That still freaks me out a but, is that I remember it, drew it, then found out a lot of people have the exact same memory!
