I am referring to the Shining edition from 1983...
I have a signed/dated edition from 1983 as well - 4/22/1983 - and the "3" looks VERY similar. The angle, the inflection, it all looks basically the same, as does the signature.
Also - both sigs have the 'period' at the end of the date.
The 4/22 is a little more cramped, but the pen is also different in both signatures...mine was likely a standard Bic type pen, and it looks like the above signature was with a finer-point.
