...oh, youse guys is naive!...
The reason I picked the '50'000' number is because the back cover of my Anchor Bay "
Supergirl" (
...I know! I know!... 
) 'Limited Edition' DVD states very clearly:
" 38983
/50,000 "
so I may reasonably assume that this set is indeed 'limited'.
If, as Dom says, the 'Signatures' constitute a limited set
within the limited set, somewhere on the disc or front or back cover there should be an indication similar to the one on my
Supergirl set, i.e.
" #27/150 "
or whatever.
I can see from your comments that none of you ever collected First Editions of books!...
