A comprehensive depiction of many memorable Muppet characters from throughout the years (and some not-so-memorable ones as well).
Each square represents a different character and indicates the primary Muppeteer(s) for that character, as well as the year and production in which the character made its debut. Borders align with hair/hat colour, background aligns with skin/fur colour, and colour of the abbreviated name represents nose colour (for characters with noses that is).
