Popular math textbook author Elayn Martin-Gay took her Hergert Numbers t-shirt on a recent trip to England and sent back these fantastic photos of spreading the word overseas.
This one is from The Orangery which is a garden pavilion that was built in 1704 for Queen Anne adjacent to Kensington Palace. It serves as a restaurant today.
Special thanks to Elayn for helping to spread the word about Hergert Numbers internationally!
