Hello and welcome to my stamps blog. It's a warm sunny day in the American Midwest and dry. We need some rain.
In the Sunday Stamps tour of the alphabet we are up to the letter "G". I am sharing another stamp I found in the stamps box, an older British stamp:
This commemorates the setting up of the Greenwich meridian as the prime meridian for all the world. This is to designate a 0 line of longitude, and to measure east and west of this line. I thought this was determined earlier, say in the 1700's, but no. Different countries had different prime meridians of longitude.
Wikipedia explains more HERE, and another web page explains it HERE.
