I've seen many, many versions of the map of Sydney, but this NRMA map had such glorious colour, it deserved to be reused. Sixty year old maps have a lot of character, wrinkles, bumps, uneven in their printing edges, but that's a big part of their charm to me. She has a Queen Nefertiti thing going on with her hairline and a crown to top it all off. Edges painted white. Sprayed with a light coat of varnish for protection but could also be framed under glass to protect the map ink colour even more.
