Is art losing its value

I think an original artwork losses its value either its been stretched or the top part of the art work been cut to fit on paper, game covers, CD covers, DVD covers or on a poster and like this picture it has been reproduced many times, its also had other things added to the picture like words, change to the colors and adding other characters to make the picture look good. This picture looks like its lost its fetchers witch means its been cut down on the left side and its also lost its original colors. I think pictures loses its value and it also makes you wonder witch picture is the original. Its kinda hard to spot the value on the picture. I also think the original picture has its value if people look harder and spot its value in the artwork its self.
