Newspaper Stamp Cancel Attribution?

Does anyone know what this cancel signifies? I know zilch about newspaper stamps, but I liked the aesthetics of the cancel.




Some examples with similar cancels at the PF:

I can offer no information, but I'd also be interested in the answer. I always thought these were not found postally cancelled.

Following.

I have no answer either but can offer this.
John N. Luff wrote;
"The stamps were usually cancelled with a brush dipped in black or blue ink. Specimens with postmarks are nearly always bogus. Genuinely used copies are scare, as the wrappers to which they were attached were usually thrown away as waste paper. Furthermore, the cancelled stamps were seldom in good condition. This is probably due to the large size of the stamps and to their having been hurriedly and carelessly affixed to the packages."

I believe that statement is meant to refer to the 1st issue of newspaper stamps, the large format stamps (PR1-8), not the later issues.

That is my understanding of them.

For those who may not be aware, John N. Luff (November 16, 1860 – August 23, 1938) became interested in stamps in his late 20's and was a collector and dealer who eventually was president of Scott Stamp and Coin among other jobs. For the last 25 years of his life he was generally considered the most knowledgeable man on US stamps in the world.

I have seen the brush cancel on ones after PR1-8

I, too, believe that I have seen the brush cancel on others after PR1-8. However, let's also observe that most of the available newspaper and periodical stamps that are available are unused examples.

Although they are very scarce, there are some known on shipping documents. However they were not always cancelled.

rev-md - I agree used are less common

There are a couple on documents in the PF search. Very few though.

Doc M Pepper in United States Newspaper Stamps 1865-1895: The Regulars ties the letter killers to certain cities, such as 'V' with Boston and 'I' with Philadelphia. The 'H' he calls 'mysterious' and asks for help from readers.

Doc's four volumes to my knowledge are the 'latest and greatest' on the N & Ps, superseding Frank Braceland's work which ran in the United States Specialist from 1966-1974.

If Doc doesn't know I guess its a mystery to everyone else, also.
