I've been creating personal display pages for many items in my collection. One of my best sources for images is the online Library of Congress website. They have an incredible collection of high resolution images that can be downloaded for free. In my page above, I found a photo of the Italian Embassy in Washington circa 1930. Also there was a great interior photo showing high level Italian officials with their pet dogs circa 1935.
In earlier times there were some light hearted moments at the embassy. Back in 1926 film star Rudolf Valentino posed with embassy officials for photos (1/29/26). Sadly, Valentino died within the year at age thirty-one.
One can appreciate historical items much better when knowing the context of the times.
