Thanks again to everyone who guessed the artists in the "Go, Speed Racer, Go!" post. There were some close guesses early on, but it looks like the Mach 5 was throwing most people off.
Jim also added Chim-Chim to the final jam piece above and I left the signatures back on to complete the picture.
Oh, and Carlos not only did the Mach 5, but he also did the flag too.
