I recently dug out my older DP Collectors guides for a nostalgic look back at my years of collecting. The one thing I can't seem to determine however, is the publish date for these guides. When checking DP guide #4 it has a copyright of 1993,1994,1995,1996. When was it published? I'm certain that I picked one up when it was issued. Also, The DP guide #3 has no date anywhere in it. Any help would be appreciated. I know that number 3 has to be pretty old as there are no email addresses or web sites listed. Just collectors selling stuff through the mail. Ahh those were the days. No ebay
