...and I'm cute too!!!
In the early to mid 1980's Applause made (to my knowledge) the very first Super Grover PVC figure, shown above left. Roughly two decades later in 2004 a very similar PVC figure was produced, and is marked 2004 on the base. This figure was then reissued in 2010, shown above right, marked 2010 on the base. It was then reissued a third time in 2014, marked 2014 on the base. I have yet to determine what company it was made by. It's possible that it was made as a cake decoration and sold with custom cake orders through grocery store bakery departments. The above two figures are so much alike that I didn't notice this variation until recently (in April 2020). Once I found out about this interesting variation, I had to have one for my collection. Below are additional images comparing the two figures.
An additional variation seems to have also been made prior to 2004 by Tyco Toys. The Muppet Wiki website has a photo of a boxed set of Sesame figures which includes what looks to be the Applause Super Grover PVC figure. Unfortunately the photo is cropped so a Tyco logo is not visible in the image on the packaging, so the only connection to Tyco is the text on the Muppet Wiki website. There's also no information about a year or decade that the gift set was made. I've noticed that on a few odd occasions the Muppet Wiki site has mis-identified PVC figures, so I'm always cautious about confirming what company made what figure. I'd like to see a better view of the gift set with the Tyco logo on the box before I've convinced it is a Tyco figure, and if the box or figure had a date on it, that would also be nice to see.
