I bought this $1 card off eBay
because of the Langley Prairie, BC cancel which is the old name of where I live (now called just Langley), and it is not that common.
When the card arrived today, I saw some sort of code it seams on the back. Then it dawned on me that it was chess moves, they were playing chess by mail. Yes I have played a little bit of chess.
I wonder how long it took them to complete the game. Now I image it is way faster, you can play by email, or just play online.
With the speed of the postal service these days, I image it would take 10-15 years to complete a game by snail mail and cost a fortune
