The Hitchhiking Ghosts Lanyard Pin (COH 001) is a Disney-approved comic published on his blog in 2010 by Ron Cohee and used for pins and other merchandise.
The Hitchhiking Ghosts are standing on top of each other, still holding their hitchhikerly thumbs up and grinning.
“I had a lot of fun with this lanyard pin. We so often see the Hitchhiking Ghosts (unofficially named Phineas, Ezra and Gus) represented just as they are in the Haunted Mansion, it's fun to give them a different pose once in a while... as long as they continue to thumb a ride to fill their quotas!
If you look closely at the art, I included their initials. See if you can find Plump Phineas' "P", Eerie Ezra's "E" and Grandpa Gus' "G"!”
