The available print has been composed from material lifted from different sources. The opening MGM credits are not the originals but a recreation using the ones from "Big Business" changing the title and certain names. Most of the film itself was lifted from elements used in the Robert Youngson compilation "Laurel & Hardy's Laughing Twenties" and for this reason the quality of the images constantly switches from excellent to mediocre, since the rest of the film was probably lifted from worn 16mm prints.
