I'll likely never own this set of stamps, but this is a perfect example of what I love about stamp collecting. I had never heard of magic squares before and I learned something new by reading this article. Add this to the list of thousands of things I have learned about culture, history, geography and countless other subjects from stamps. I am an insatiably curious person and philately fits perfectly with that mindset.
