We all know the illustrations Baynes did for Tolkien (and Lewis) books. She also drew the map of Middle Earth. If i remember well they did a limited printing of this map (100 pieces) of which 3 were signed by both Baynes and Tolkien. Does anyone have any info on this.

Do there exist any other limited Baynes (Tolkien) related items? I got the Middle Earth map towel... but also there have not a lot of info.

I'm trying to get a Baynes - Tolkien article ready but i'm missing good informations. Should i go and dive into any specific archive or write someone specific to get the info?
