The twenty-third is my birthday, 1-23-41, so 23's have always been special to me - my lucky number.
Good idea - collecting interesting numbers. Perhaps they all are.
I also like ampersands.
My favorite ampersand is Bernhard Modern. Truly, ~Diane
P.S. I posted your beautiful photograph of a beautiful church in Paris on my Facebook page. For the moment I am unable to find it again. Will keep looking.
