Breyers have been pictured in the Sears Christmas catalogs from 1954-1970, 1972-1992, 1996-2000. The years that appear to have no Breyers pictured are 1971 and 1993-1995. If you have more information or photos, please contact me.
Fun fact: The 1971 Sears Fall/Winter catalog has the bay (#15) and alabaster (#9) Family Arabian Foals posing on some shelving units! These models were actually never sold by Sears!
