As the subject says, I'm looking for a list of all line pairs or joint line pairs. I did a search on the internet, but was unable to find such a list.
Thanks!
re: Looking for List of All Line Pairs or Joint Line Pairs
If you have a Scott Catalogue, any stamp listed as a Rotary Press Coil, up to 1962, will have a joint line.
Or, see this posting on The Stamp Community, where someone has listed all the US and foreign stamps printed on the Stickney rotary press. https://www.stampcommunity.org/topic.asp?TOPIC_ID=50076
