These are postcards I received in 2017.
The longest traveled card is form Hapur, India, which traveled 9,231 miles and took 19 days to arrive.
The one that took the longest to arrive is the card from the Netherlands which finally appeared in my mailbox after 74 days.
The card to arrive the quickest was from Dusseldorf, Germany and arrived in just six days.
My favorite is the Gustav Klimt card.
I've sent and received close to 800 postcards from around the world through Postcrossing.com (a wonderful free site).
55,000,000 postcards have crossed the world through Postcrossing--it is the best site on the internet (besides List Challenges, of course).
