Golden Age Blonde Phantom (Louise Grant)

First appearance: All-Select Comics #11 (Fall 1946 issue, on sale September 26th, 1946 according to the GCD):


All-Select Comics was a quarterly title that originally featured stories of Captain America, The Human Torch, Sub-Mariner (depending on the page count?), and usually another feature (such as The Whizzer, The Destroyer, etc.)
But with issue #11, The Blonde Phantom was introduced and appeared in two feature stories.





Also in issue #12 were features starring Mister Wu and Miss America (Madeline Joyce).

Issue #11 was the final issue of "All-Select Comics". Beginning with issue #12, the book was renamed Blonde Phantom Comics and would stay that way through issue #22 (cover-dated March 1949).




NOTE: Starting with issue #23, the book would again be re-named, this time to "Lovers".

It looks like Blonde Phantom's last Golden Age feature story appeared in Marvel Mystery Comics #91 (cover-date April 1949):




It wasn't until about forty years later that the Blonde Phantom would start appearing again as a character in new stories from Marvel (though readers may not have realized who exactly she was at first):


from Sensational She-Hulk #2 (June 1989)

And here's the entry for Louise Mason that appeared in the Official Handbook of the Marvel Universe Update '89 #5:

As I recall, Louise ended up getting together with She-Hulk's dad, Morris Walters!
