Poor Pamela! She welcomes the world with arms outstretched, but somehow, she just looks a bit odd. She is what a doll collector would call a 'clone' - a copy of a popular doll. The popular dolls in question are 'Flatsy' dolls.
These are curious in themselves - flat dolls in cute outfits, they appeared in 1969. I think they were more popular in the US than in Britain, and they have been recently revived (here)

Odd, for sure, but you can see that they might have some appeal.
However, in trying to copy the dolls closely, but not too closely (in case they get sued), the creators of 'Pamela' have just missed the mark.
