Disney car decal search.?

i'm currently looking for a car decal/sticker. I saw a lady driving a car with a decal on her window that had Cinderella's castle on it, and it said "i'd rather be at disneyworld" or something to that effect. i cannot seem to find one. it was a white outline style. i've found the ones with the people with disney ears on, but i'm specifically looking for that castle one. any help would be great!
