World Hockey Association Autographs

These are my autographs of players who only appeared in the World Hockey Association and not the NHL. I really wish ITG would have made a WHA hockey card set before they were bought by Leaf. I think a WHA themed set would be a big hit among collectors. I still have a long list of players WHA only player autographs I need and a set would surely produce some unique signers. Unlike former NHLers, it can be hard to locate WHA players as not many people write to them. Especially the ones who never played in the NHL. Its also hard to find pictures of some of them.
If you don't know anything about the WHA then you should look into in. It existed as a rival to the NHL from 1972-1979 but experienced many difficulties. Legends like Gordie Howe and Bobby Hull spent a significant amount of time in the league. The Rebel League by Ed Willes is a good book written about the WHA.
