In 1969, Yoko Ono and John Lennon invited the public to join their honeymoon as it unfolded in a Montréal bedroom, complete with a song-writing session with Timothy Leary. This was the start of the couples' iconic bed-in series, and a showcase for what would become one of Ono's favorite concepts: Peace.

Today being the International Day of Peace, Ono isn't missing her cue. Art Production Fund and Ono's anti-fracking Imagine Peace initiative have arranged to broadcast the words "Imagine Peace" hourly across the three largest screens in Times Square all day today, through an initiative by the Times Square Alliance public art program. American Eagle, MTV and Viacom will be displaying the message in 24 languages, so polyglots can rejoice.

In an e-mail to The Huffington Post, Ono said her wish for the Day of Peace is "for all of us to think peace, and allow each other to be peaceful at the same time. Even if it was for one day out of the year, it will have a great effect on our planet and the Universe."

She also wrote us a short poem:

Peace makes people smile, and the nature shine.
It covers our world with wisdom and love
It is the most beautiful thing in life.

To honor the artist, we've collected a few of her best quotes about peace (and one iconic Lennon one) and matched them with our favorite images. Click on the slideshow below, and let us know your thoughts in the comments section.
