1933 mickeys pal pluto artwork

[viper1891]

hello everyone! hopefully i am in the right thread but anyway a few years ago a came across this movie artwork from mickeys pal pluto cartoon. it looks the same as the movie poster but the graphics are printed in color on a mirror. i would say its about 2 feet tall and 1 foot wide. on the back there is a paper lining that looks fairly old and it says disney 1933 and gives another name of a place (i think where the cartoon was published) anyway i actually think its pretty old. its in very good condition and i have not been able to find anything else remotely like it! if anyone has any info on it and how much they think its worth it would be greatly appreciated. thanks!!
