The Bennington Museum recently posted "backroom tours" online. They are called "Tours at Ten and More" and give you a sneak preview of their backroom.
The one I watched and really peaked my interest was "Stoneware in Storage". This featured a 1864 12 gallon presentation double handled jar made in 1864 marked and for Calvin Park.
But what interested me was cursive writing on the jar. Jamie Franklin gives us his interpretation of the meaning of the script on the jar. For me I was looking at the script style, especially of the "J's" that appear on all "Little Brown Jugs". Look through this site and compare, I find it fascinating....
