Wanted: Original Super Grover Plush

[Larxene]

I know I had one as a child in the late 70's but I can't seem to find one on Ebay or even a picture of one. I remember the grate on his helmet was a seperate piece but not much else. In any case, I'm looking to buy one! Grover is my favorite Muppet and I'd love to have this plush back in my collection.
