When I was a child, I wanted to grow up and be an artist--but not just any old artist. I wanted to be the artist that Hollywood producers called when they needed artwork for their movies (as in, the lead character is an artist, but my artwork would be shown as theirs). I had no idea how that all worked--I really thought that was a specific job you could have ("What do I do for a living, you ask? Well, have you ever seen critically-acclaimed, box office smash Movie About an Artist? I was actually the artist behind the Artist.").
Alas, I'm not working for a studio, and my artwork doesn't appear in the movies. But, there IS hope. Check out Fauxgo, a Tumblr of logos of companies that exist only in the movies. Lots of Pixar love here, Toy Story, Monsters Inc, Up and Wall-E are all represented; as well as huge pop culture icons Dunder Mifflin, Sterling Cooper and Oceanic Airlines.
I'm checking back regularly to see what else gets added. Who knows, maybe one day that will be my claim to fame.
