In 2014 English auction house SPINK sold photographic archive of no longer existing printing house BRADBURY WILKINSON on a private auction. This set had made in the era photographic copies of projects, that the printing house worked on, but never went through the acceptation phase. Thus, due to this sale, this unbelievable set was able to "see the daylight". Among this set was the unknown before banknote with Józef Piłsudzki and Ignacy Paderewski. Due to its' historical value, it is a piece that is extremely important for the history of polish paper money, worth being shown in a museum.
Format of the print ~ 135 x 75 mm. More info about these photo-projects here
