That stamp is just too precious--almost makes me want to shout, God Save the Queen
Inside the main envelope is a smaller envelope with its contents labeled:
The (unused) Buckingham Palace toilet paper--magnificent. Val knows I love quirky mail art, but he has really outdone himself with these two royal treasures. Great patriotism and great sense of humor--a perfect marriage for mail art. Merci beaucoup, Monsieur Herman!
