I am searching for any WWI or WWII memorabilia as is ads, papers, books, artifacts. Not copies or re-makes. Not looking for anything that should be left in the ground, or pilferaged, like I saw in France. Mostly interested in WWI, as my grandfather was in the war and my BF is a professor of history.
Is one market, such as Portobello a good choice? Or, should I search out antique shops?
