My collection of images from the year 1933 has grown a lot lately. For a long time I'd been using the search terms "country 1933", and this worked okay, but Google has changed thier algorithm or something, and I see a lot of the same images in groups. I'm sure they're just trying to be helpful?
So it's a little more work now- I have to be more specific, so I've been looking for other terms plus the date- say, for example, policy books.
the Policy was what would later be called the Numbers, and most of us only know about them from movies or TV, but in the height of the depression these lotteries were huge. Dream Books were an ancillary con. If you'd dream of a particular word or phrase or image, you could look it up in your dream book and play it.
If you didn't hit your number, you might consider selling the books...
