Anyone have any idea when the story in which Clark revealed his identity to Lois and they got married was published?

I've heard about this story...and something about how much later it turned out all to be a dream or something? I am way too young to have read these strips when they came out (I guess I could have read World's Greatest Superheroes...but for some reason I didn't). These strips are a fascinating read, and this story is just one more example about why attention should be given to them.
Anyways, I have yet to come across it. I have read a full decade of the dailies (3,000 strips so far), and am now fully into the Wayne Boring era. I would bet it would be sometime in the mid-fifties, but my predictions have been wrong everytime I made a guess about the strips so far

The stories keep me surprised at every turn...
I'll be sure to let you know if the story appears in the next 18 months that I have yet to read (then it's back to tracking down or begging others for more of the strips).
I'll keep updating the site.
Thanks.
