David Overton has an understandable interest in fabric maps since that is what his business Splashmaps make. He was recently at the University Library in Cambridge viewing their maps collection when he stumbled on these incredible silk European nautical maps complete with instructions on how to build your own raft (presumably if you got shipwrecked or shot down).
“Got very snap happy there ;-). No doubt a blog is a-brewing.. sneak preview? This combined one had full european silk sea charts PLUS instructions on building your raft! From #ministryofwar #ww2 #genius!”
