1993 Limited Edition Royal Mail Year Book

Since 2003 the annual year books have been sequentially numbered. Numbers 1 to 160 have been leather bound. The standard version begins at number 161.

Prior to 2003, limited edition versions of the year books have also been released. I have personally seen them dating back as far as 1993. As they are not numbered, I cannot be certain if they were issued in the same edition of 160 or not.
