Traditionally this would be in the form of food or craft goods that is a specialty of the area. Now it can be a trinket with the place name on it, (even if it was probably made in China.) When Tokyo Disneyland opened, it was the first Disney park that had the (geographic) place name on its souvenirs. If you go around Waikiki, something you can find are bundles keyrings, mostly so Japanese tourists can easily grab a couple of those.
As cameras came about, this practice has expanded to bringing back photos since it is a form of sharing your travels with people at home.
