Wow, age 3 is young. Nice thread by the way.
1965 for me at age 5. I can remember them and I really liked the pennant design. I still have some in the collection but they are all collector grade as I used to keep them in a red suitcase and would sort them by team and then Mom would throw them into the suitcase and I would sort them again.
Probably peaked in 68 and 69 but collected up until 74 and then HS and girls became the priorities. And I still have that red suitcase. It has a bunch of 69 decals on it as well as 67 Red Sox stickers. Priceless to me
