does anyone know what mmtpcritterchristmas stamp might be?

I have, at some time, downloaded a picture of a card with a cat with a santa hat on and a mouse with a mistletoe and all I have listed is mmtpcritterchristmas and I have no way to find who made the card or the stamp it was made with.  If anyone knows the site I can go to I would really appreciate the help in locating this.  Please email me at lenoriakelly@att.net with any info.  Thanks a bunch!
