There's a beautiful map store in London that I visited. If I recall, everything in there are contemporary "originals" -- meaning printed in that year, no re-printing. So a 1973 map of the Underground was from 1973. They also had very old, beautiful maps. I wanted them all!

After 20 minutes, I began to realize my wife was casually leafing through dozens of poster-size maps with £30,000 price stickers on them. My jaw nearly dropped. Her hands held "art" that they valued at close to £500,000++. I also realized I couldn't afford the map I wanted and left empty-handed
