Translation of the text on the sign:
[City emblem of Giv’atayim]
Avraham Aldema 1884-1963
Zahava Aldema 1901-1995

Avraham Aldema, a member of the Second Aliyah, was an artist and art teacher at the Herzliya Gymnasium, one of the early activists in the Haganah, and a pioneer of cultural life in the city of Tel Aviv.
In 1922 he was among the founders of the Borochov neighborhood. His house was unusual in its structure compared to the other founders’ homes.
In 1923, a large "Slick" (underground weapons cache) was dug and built in the yard of the house, in which hundreds of weapons were stored. The ventilation opening was camouflaged by placing a dovecote above it. The "Slick" was the largest weapons cache in the Tel Aviv area and remained in use for 25 years, until the establishment of the State.
In the house, members of the Haganah in the Tel Aviv area took their oaths, and it became the unofficial headquarters of the Haganah organization in the Borochov neighborhood.
In 1925, Avraham married Zahava Yudlewitz, a pioneer from the Third Aliyah, a member of the "Women Workers’ Farm" in the neighborhood, a Haganah member, and later named a "Worthy Citizen of Giv’atayim." After their marriage, Avraham and Zahava dedicated their home to serve as a cultural center, which became known as the "Aldema Courtyard."
In the courtyard, they built an amphitheater with 800 seats, which hosted plays and performances by the theaters "Ha-Matate" (The Broom), "Ha-Kumkum" (The Kettle), "Ha-Ohel" (The Tent), "Habima," and others.
