This edition and the photos of it were contributed by a visitor. Thank you!
The Roman numerals for the year shown twice in the photos are not standard and don’t ‘convert’ with a tool such as this. This Roman numeral quirk has been seen in other editions, originally discovered in this 1910 T.N. Foulis Maurice Greiffenhagen Miniature Edition. Basically, you just add it up normally, ignoring the ‘four’ rule.
