No problem :)
I used it as an example to show how cancellations can be used to date a cover. Here's a pic of the cover in color. In fact, another way to prove that this is an early use is that the small Boston "PAID" is in red. This cover was used barely more than 2 weeks after issue from Boston to Windsor, VT. Windsor is a small town today but in 1851 it was one of the largest towns in Vermont.
