Approver Comments:
I agree that this is the Hersz Majteles who signed the album; born in 1929, he would have been 12 when he signed the album, an appropriate age for school #13B.
Also note his addresses: Moltke 67 and Reiter 23, apartment 12.
In the future, please use the comment box to explain how you determined that this was the student who signed the album.
