APB, very helpful information, thank you, Ill try to track it down there at the British Library.
Lissa…the “tape” is not Scotch® Brand tape, it is archival tape and is quite simple to remove with mineral spirits and commonly used as a temporary strengthener for old papers. I did not put it there, I tend to leave tears as they are but Im not too worried about it, unless the tear is at a hinge where not repairing it will likely result in further damage. You are correct in pointing out that normal plastic tape contains acid and will literally “burn” the paper causing browning over time, and is also quite difficult to remove without causing significant damage to the paper underneath. Acid free tape is available, but it too is difficult to remove without damage.
How to tell a fake:
- Try to ascertain if there would be sufficient motivation to fake such an item
I believe it is unlikely that someone in the 18th century would produce a fake newspaper, not only would it be a laborious and expensive task to set up, but as earlier noted in this thread, something more sensational probably would have been printed in it, such as an actual account of a witch burning or some revisionist politically motivated message (like holocaust denial). Before the 19th century, paper was hand made, and very expensive, so it tended to be only utilized by more official publishers. Finally, the value of such an item in 1700’s dollars would be so low that it would hardly be worth the effort.
- Look at what else the person you are buying the item from sells.
In this case I bought this item from a dealer who guarantees the authenticity and has been selling antiquities and rare documents for 35 years.
- Compare the composition and style of the item to other items from that period if possible.
The paper has a high rag content and is heavily texured, it is clearly at the latest 18th century. Early 19th Century paper is smooth and tends to be quite brittle and thin, as the effects of various bleaching techniques was largely unaccounted for in production.
Another way to tell its genuine, using a magnifying glass, you see that the letters actually are “impressed” into the paper, meaning the only way to produce it would have been by laying out all the letter blocks and running it through a printing press. A lithograph is pressed, but doesnt tend to create individual letter impressions because the system doesnt depend on the same amount of pressure to make an “impression”. Modern printers “spray” the ink onto the page, meaning on the microscopic level the edges will have an even blur to the edges, and you will likely see faint lines running across the black ink parts showing where a printer head has moved across the page. Also, since the printer head is “spraying” the ink on to the paper, small bumps or crevices will alter the shape of the lines, making them appear a bit crooked where the bump is, whereas squishing the paper with a press will force the exact shape of the typographer’s block regardless of bumps or whatever in the paper. This is how you tell if someone printed something recently on an old piece of paper.
Thanks again to all for the information. This is a great forum!
