this page includes two actual postcards - starting at the top left, there is a 1971 dodgers postcard (sometimes referred to as a 'dexter' postcard), a 1972 jd mccarthy postcard, a 1975 mengler baseball's best 'card', and a 1975 sspc puzzle back
i wrote a little bit about the mengler card here, which is to say i provided a link to a different source.
here are the backs, although they are reversed. that's the back of the jd mccarthy card in the upper left. the puzzle back piece is of nolan ryan's torso.
this next sheet is chock full of actual postcards, all issued by the dodgers. based on what i've been able to find on the internet, i believe they are (starting in the upper left) 1975, 1981, 1977, and 1976 issues.
in the meantime, here's another sheet from the binder. this one includes a 1987 jiffy pop disc, a 1987 m&m's star lineup uncut panel with fernando valenzuela, a 1979 metallic creations card, and a 1979 baseball patches patch of the garv
the metallic creations card is sometimes referred to as a 'signature miniature'.
time for one more page. this one features a really cool 2003 donruss card that was only available when you subscribed to the dodgers' magazine and a manufactured patch/auto card issued by upper deck as part of the 2002 world series heroes set
