No. 333 - arriving mail art "Arcimboldo war nicht der Schlechteste" from Uli Grohmann (Germany)

No. 333 - arriving mail art "Arcimboldo war nicht der Schlechteste" from Uli Grohmann (Germany) - Uli used a caricature of Bismarck which refers to the style of Guiseppo Arcimboldo. There is no senders address, but I think his typical flies identify the sender. Thank you very much
