Wanted: A few good subway maps

I’m currently working on a post about the evolution of the New York City subway map and the various ways in which station location and geographical information are presented on maps from around the globe. I’ve come to the realization though that I do not have a few maps I might need for this project, and so I’m going to attempt to crowd-source. Do you, loyal SAS readers, have any subway maps from the early or mid 1990s lying around? Do you want to find a new home for them (or lend them to me for a bit)? If so, please contact me.
