No, the left is NOT mustard. Everytime I post this color I get ninety responses from people thinking I'm selling a mustard yellow for practically nothing !! ----- Three CD 102 Diamond ponies in shades of green as shown. Left has small flat base chip. Middle has flakelet where base and skirt meet. Right has small flat base chip with nice bubbles in front skirt. This is mentioned for accuracy as basically these are all mint !! Take all three for $35.00 + shipping. First email that says' "I'll take it.". No PayPal. Email with questions.
