The "Ocean Chart" is not necessarily made by Henry Holiday

The poem and the illustrations have been published by C. L. Dodgson (aka Lewis Carroll) in 1876. On the cover page we read: "With nine illustrations by Henry Holiday". However, there are ten illustrations.

That is no mistake: Among these ten illustrations (plus the two front-cover and back-cover illustrations), probably it is the Bellman's Ocean-Chart which is not made by Holiday. I assume that Dodgson commissioned a typesetter with arranging that map.
