Big yes.
I have sets going back to 1982.
The 80s Guide Maps were wonderful.
Some of my faves :
EPCOT Center original 1982 cardstock *wheel map* ( original 1st version )
EPCOT Center 1983 cardstock * wheel map * ( second version, inner visual difference )
MK 1985 Guide Map ( more like a detailed booklet, with lots of photos and through descriptions of all attractions)
Disney/MGM Studios Dec 1989 Guide Map ( two versions, both with different early photos )
EPCOT 25th Anniversary map ( only availible Oct 1st 2007 at the Park )
It is interesting when you have been visiting the Parks often and collect the Guide Maps over the years. The changes are very pronounced, and the different attitudes in marketing the Parks and attractions over the years becomes clear when looking them over.
Today*s Guide Maps are so simplified compared to the info-packed versions of yore. Sign of the times...and it just shows most Guests already read up on their visit long before entering the Parks.
