Banco López was a private Colombian regional bank operating out of Barranquilla, and by 1919 it was already operating on borrowed time. Colombian banking law had been moving toward centralization for years, and the Banco de la República would be established just three years later in 1923, effectively ending the era of private note-issuing banks in the country.

The American Bank Note Company contract is worth noting — Colombian regional banks frequently used ABNC for prestige and security printing, and the plates were expensive enough that some institutions reused designs across denominations with only the value altered. Whether López did so across this series is worth checking against S575 and S576.
