Hi everyone, and thanks for the spirited discussion. Not to split hairs too much, but both Scotts and Stampsmarter refer to March 27, 1869 as the earliest known date of usage. I am just curious why I can't locate the date the stamps were actually printed and distributed? It was probably very close to that date, but does anyone know for sure?
I checked Brookman, Volume 2, and it only references the Scott's date, and the small snippet here:

So, of course, February 25, 1869 is not possible, but I wonder if earlier in March is out there somewhere?
