In
2014, the english auction house SPINK sold photographic archives of
nowadays nonexistent printing works BRADBURY WILKINSON & CO. These
archives included photographic copies of projects of notes, which were
to be printed, but the project resulted in failure and, as a result,
these notes never went into circulation.
