Collecting vintage signs is the sort of thing that many people love to do. They know that these signs are real examples of the history of our world, and since many businesses that were up and running a few decades ago are indicative of the socioeconomic conditions of the time their corresponding signage can often end up being powerful examples of things that we used to do and beliefs that we used to trust so blindly in spite of the fact that they might not have been accurate to the actual realities that govern the world that we all share and inhabit.
You don’t want to just buy any random vintage sign though. The truth of the situation is that the best signs are going to be the result of accurate and widespread research. If you want a collection of old signs that is going to be truly phenomenal then you should first start by looking into different geographical locations. Focusing on just one area is not going to a good idea. The vintage signs from Texas are going to be very different from the signs that people used to use in New York.
If you only focus on one area then you are doing yourself a huge disservice because of the fact that you are ignoring the vast quantities of knowledge that can be gained from spreading out a little in this regard. Instead of just focusing on different eras, try sticking to a single era and collecting signs from different cities that were used during these time periods so that you can get a wider view of society rather than becoming myopic due to your preference for your immediate surroundings.
