If someone is interested, here you can read three articles which are related to this vignettes (all of them are about Mexico):
https://independent.academia.edu/CedrianBosch1) One on Fernando Fernandez, the Mexican engraver who at the time was person responsible to take care of the technical aspects of the banknotes for the first attempt to create a Central Bank in Mexico. He traveled to Canada and hired the BABNC to produce the plates (unfortunately, when I wrote this piece, I had only few hints of this)
2) These proofs of the banknotes that were intended to be issued for such a bank. There are two different sets; everyone (myself included) thought they were two alternative designs and that the Mexican authorities favored ABNC over BABNC, nevertheless, I found that the intention was to issue both, first the notes printed in the US and then import the machinery, paper and plates to print in Mexico those engraved in Canada. Unfortunately, the bank was never established.
3) The alternative use of the vignettes that were produced in Canada and the paper manufactured in the US for that bank.
Hope anyone here find it interesting.
best,
