Posted on the right is an interesting review of Charlie Chaplin, a 1951 biography:
"[Chaplin's] first pictures were made in the Keystone studio, 'hardly more than an open platform with the sun diffused by muslin sheets hung above.' Mabel Normand at first refused to go on with him, remarking that he looked like 'a package mis-sent.' But his rise and development were steady."
