Every summer during an annual family trip to Maine, I stop at the giant Undercover Flea Market in Oxford, ME.
While browsing last summer I came across a ledger book with several beautiful samples of what I would call a Spencerian business hand. It's very compact, practical, and relatively "rapid," but the writer still took time to make some delicate shading and finely-formed capitals. I absolutely love the M in "Massachusetts."
It caught my eye immediately. From a paleographic point of view, I absolutely love seeing clearly identifiable scripts "in the wild." From a penman's point of view, it's just beautiful to look at.
Though most of the samples were not as fine as this, the book was not expensive and I still regret not buying it...
I'll be there in a week--maybe it will still be there!
