No research can be conducted without references to read and learn from.
For the Breyer Box blog I have used the following books as help in determining dates and packaging:
"Breyer Horses, Riders & Animals Molds and Models" by Nancy Atkinson Young
"Breyer Models Reference and Insurance Guide" by Marney J. Walerius
I have also used numerous Breyer animal Creations Dealer catalogs from the 1970s through today. Mainly the following years: 1971, 1972, 1975, 1980, 1981, 1982, 1983, 1984, 1985, 1986, 1987, 1988, 1989, 1990, 1991, 1992, 1993, 1994,1995, 1996, 1997, 1998, 1999, 2000-2010, as these were years available to me. This list will be added to as additional catalogs become available to me.
Identify your Breyer (http://identifyyourbreyer.com) has a wide range of Dealer Catalog scans available online which were a valuable resource to me until I was able to acquire many of these catalogs in print for my research.
Many many thanks to the members at Model Horse Blab (http://www.modelhorseblab.com) for their hours spent sending me photos of the boxes in their collection. Another of my main resources is the Breyer Box, Ad and Sticker gallery which I run, which would not be possible without the people of MHB. Their knowledge and thoughts and comments on boxes is valuable help to me.
Photos displayed on this blog will be credited to their source as they are posted.
Additional references will be added to this post as they become available.
if you have further information about boxes, packaging or breyer history, please feel free to contact me.
