I am trying to identify what exactly "vertical laid lines" are on the Scott #73. I have found some auctions online but cannot find any actual description. I understand this was the first printing. Other than that, I can't find any real information. Any help would be appreciated.
Searching this site is like searching my son's room for a clean shirt. Countless "is this laid paper" posts but no real explanations. Many of the posts don't even conclude that a stamp is or is not on laid paper. But, I did some internet searches and found some pretty good images. Thanks for the reply Peter.
