 This cartoon was colorized in 1968 by having every other frame traced over  onto a cel.  Each redrawn cel was painted in color and then photographed over  a colored reproduction of each original background.  Needless to say, the  animation quality dropped considerably from the original version with this  method. The cartoon was colorized again in 1990, this time with a computer  adding color to a new print of the original black and white cartoon.  This  preserved the quality of the original animation. Also, the ending was  cropped: after Porkys police car douses the white Ghost in exhaust soot, it  originally turned toward the camera appearing as in Blackface and remarked,  in a voice like Eddie "Rochester" Andersons, "Mah, oh, mah!  Tattletail  grey!"
