One of a Kind! Dedication by Rabbi Aaron Zvi Grass on an Extremely Rare Illustrated Children's Book, the Eve of the Holocaust, during which the Gaon Perished

Ivri Anochi [I am a Hebrew]. Vienna, 1931. A textbook for teaching Jewish European children Hebrew. With colorful illustrations. Extremely rare!
At the beginning of the book, a dedication handwritten and signed by the Gaon Rabbi Aaron Zvi Grass, Av Beit Din of Pamaz (1905-1945), author of the book "Kol DeAmar rachmana" which was printed in Budapest in 1936.
It can be assumed that the child who had received the book from his also perished in the Holocaust.
