On the back – autograph of the photo’s owner O. Tsareva: “Dear editors, please send this photo to the Museum of V.I. Lenin. Its history is as follows: the pioneer squad of my class was named after N.K. Krupskaya. I invited M.S. Yakovlev to the pioneer meeting. He saw N.K. Krupskaya and took a picture with her at the congress. He and F. Ldokova (?) told a lot about her. Both are now deceased. And I have long been retired. I want this photo not to get lost. Please answer me: 459210, pos. Borovskoy, Kustanay region, st. Koroleva 8, _B. 15, Tsareva O.”
The photo belonged to M.S. Yakovlev who is on this photo too. He presented the photo to O. Tsareva, who sent it to the editor of an unidentified edition for subsequent transfer to the Central Museum of V.I. Lenin.
