Rare A Hard Day's Night? | Fab Forum

Has anyone ever seen this?
I have a copy of A Hard Day's Night that I cannot find duplicated anywhere.
Firstly, it is listed here, but my copy has a difference that no one out there seems to either have noticed, or cared about.
I can't imagine that I was the first to notice it in 55 years.
The copy I have is marked at UAL 3366 RR4M.
Here is the weird thing:
On side 1 the title is written without the apostrophe.
I have "A HARD DAYS NIGHT" instead of "A Hard Day's Night ".
Side two is correct.
I have seen pictures out there of the same UAL 3366 RR4M label without the mistake.
So, am I crazy, or do I have something rare?
Any help would be great as I try and sell my father's records.
