18 vintage US postcards that will take you back in time

There's nothing quite like a walk down memory lane, or a hit of nostalgia for the better, simpler times you weren't even around for.

Luckily, the Boston Public Library is making this easy for us, as they uploaded a collection of 25,000 vintage postcards from the 1940s to the 1960s to Flickr. These Tichnor Brothers postcards offer a blast from the past through images of iconic cities and tourist attractions.

Instead of having you peruse the 1,000s of postcards, we've picked out some of the highlights. Here are 18 of the most iconic vintage postcards that will take you back in time.
