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.
