This is a cast photo from the first season of The Partridge Family (1970-71). The actor in the bottom left corner is Jeremy Gelbwaks, who played Chris Partridge in only that first season. (He was apparently hyperactive and uncontrollable. Years later Danny Bonaduce referred to Gelbwaks as 'psychotic.' Brian Forster replaced Gelbwaks in the second season.) Susan Dey's pretty face is quite appealing.
