This post is both sweet and sad--I doubt any reader will go through the whole thing without feeling any emotion. I certainly can't, I feel these photographs especially. The theme is, of course, love, specifically the kisses of farewell and welcome home.
All of these come from Australia, for no specific reason except that the curators of Australian online collections seem to be just as touched by these photographs as I am. Some are from the State Library of New South Wales, found here on the Flickr Commons, with their own site here . The others come from the Australian War Memorial collection-- their website, and their collection on the Flickr Commons.
I'm not going to say much, because these really speak for themselves.

My very favourite. A kiss interrupts the march of troops through Melbourne, 1943. Source [or, to view very large, here... it's great to see the smiles on the faces of the other men]
I hope all the men saying goodbye made it home.
