Any statement made in this forum is of the posters opinion, as for the word Vintage, it is defined as "representing the high quality of a past time".
Additionally, a 1920's collector may scoff at the term vintage used for a 1960's collector etc..., so how do we satisfy the masses.
In my opinion, anything prior and up to 1989-90 is a significant time to put the word vintage. At this point in time we have a minamum of 18 years gone by, which is the age that most officially turn into men. (funny thing is, I am 44 and still don't know what I want to do when I grow up...hehe)
Just "A" suggestion which is similar to the comic classification in this order of their respective vintages.
1910 to 1950 - Bronze Vintage
1951 to 1971 - Silver Vintage
1972 to 1989 - Gold Vintage
1990 to present - Platium Vintage
Each of these era's are significant in thier own right, I feel most of the forum is within the Silver age (not necessarily related to turning grey haired... but close).
The second maybe tied between the Bronze and Gold era's.
Lastly the Platium is possibly the lease collected era that visit this forum, however that is not to say that some of the other era collectors' don't collect new cards, many do so for autographs and such, so lets face it, it is still hockey, something we will always have a love for.
Any opinions are more than welcome.
Here is a VINTAGE photo of me and my brother in 1973...
