Examples for advertising the 1st edition of “The Hunting of the Snark”, then offered for €200 and more:
First edition, first printing, with “Baker” for “Banker” on page 83.
First issue with “baker” not “butcher” on page 83. It is unknown how many copies were printed this way.
This is about line 560 on page 83, the last page of Lewis Carroll’s tragicomedy. All copies are printed this way. And in Henry Holiday’s illustration on page 82 you can see the Baker.
So there is nothing special about “Where the Baker had met with the Snark.” Those rare book traders just don’t check the facts.
Then there is the JubJub. If you read somewhere that the bird never will look at a “bride”, then better check line 386 on page 55 in the original Snark edition.
