The Mother of all blog posts

Mother's Cookies, that is. Part of my COMC Black Friday haul was some Mother's Cookies Hershisers. No, I can't tell them apart.  But I knew that I didn't have them.  Now I do.

1988 Mother's Cookies LA Dodgers
Orel Hershiser (card # 6)

1989 Mother's Cookies LA Dodgers
Orel Hershiser (card # 6)

1990 Mother's Cookies LA Dodgers
Orel Hershiser (card # 12)

1993 Mother's Cookies LA Dodgers
Orel Hershiser (card # 10)

1994 Mother's Cookies LA Dodgers
Orel Hershiser (card # 7)

I also get confused by the names that COMC gave these sets.  The 1988 card is from the LA Dodgers.  The others are from the LA Dodgers Stadium Giveaway [Base].  Hmm.  My guess is that the cards were included in the product and given away at the stadium, but I don't know for sure.  Anyone want to venture a guess?
