(Please continue reading with my Januari 2011 posting where Viktor Pirkhoffs identity thanks to this article is discovered and shown in 4 posting !)
His tulips in a vase might have been inspired by Hugo Noskes print (right).
The flower bouquet resembling stylish Martin Erich Philipp (right). I think this is the first time prints of this artist are seen together.
(Table cloth and curtains alternated)
The third print I found browsing at Findart.com. I think they will have no objection showing it here.
The subject (epiphyllum blooming) choosen by Philipp and Noske too. Maybe some day Pirkhoff's identity who, judging by these 3 prints was a very skillfull printer, will be revealed.
