Czaplowizna - The fruits of the last Summer - Janusz Korczaks Orphanage - 1940

"We hereby certify that the potatoes and vegetables are the property of the Orphans Home in Warsaw and are transported to Warsaw to us from our colony in Czaplowizna at 1 Klasztorna street, Municipality of Wawer."

The only known document, a bilingual letter, signed by Janusz Korczak both with Goldschmidt and with Korczak signatures. The letter was a kind of epilogue for the Summer camp Rózyczka. The letter was addressed to German authorities. The document was issued to Jan Zalewski. 

Later, Korczak started to use a rubber stamp with both names as signature!
