I was super surprised to stumble across these.

Amazing finds! Interesting they spell Tannis's name with two 'n's. I wonder if everyone has just been getting the spelling wrong all these years, or if they changed it for what we see on the model sheet before it was released.

Many of the sheets have red date stamps with minor changes, but I don't think hers is ever stamped. How do the end credits spell it?

Edit: the movie doesn't list the character names!
