New images: Marci letter wax

[Jorge_Stolfi]

it is too difficult to get the scale correct.

The VMS pages are said to be ~235 mm tall.  On most single-page BL 2014 images the tallest pages are ~3570 pixels tall, which gives a scale of ~15 px/mm or 386 px/in or 0.0658 mm/px.

For the Marci letter, one could get a rough estimate from the folds reported by Rene, assuming that they were meant to make the letter fit inside the cover. 

All the best, --jorge
