In 1919, Pennsylvania required all non-residents to purchase a license when fishing. It was not until 1922, when residents were required to have one. In 1935, the non-resident tourist license was introduced and was good for 3 consecutive days of fishing. There are also Complimentary licenses that were issued to people of importance, such as governors, presidents and executives from other state agencies. I have seen examples of the complimentary licenses, but from what I understand, there were less than 50 issued each year.
On my site, I only take a look at NON-RESIDENT and NON-RESIDENT TOURIST. That does not mean I am not interested in RESIDENT licenses. Almost any collector interested in licenses is working on or has completed a set of resident fishing licenses. I am no different. Much is known about resident licenses, and completing a set is quite feasible.
