Postcards purchased at Glacier National Park

Given the number of postcards for sale in gift shops, even people who do not normally write letters must still write and send postcards on their vacations.  Perhaps postcards are the Twitter of snail mail. Both accommodate only the shortest messages.

I still enjoy sending and receiving postcards.  I often buy one or two for myself as souvenirs of my trips.  I like the vintage-like art on these postcards from Glacier National Park, which was celebrating its 100th anniversary this year.
