Final answer:
The personal oil paintings were exhibited at the Grolier Club in New York in 1962, donated to The Metropolitan Museum of Art, and also showcased in prominent collections such as those owned by Gertrude Stein or displayed at the Smithsonian Institution's Hirshhorn Museum.
Step-by-step explanation:
The personal oil paintings of the subject were exhibited at several prestigious locations. Initially, a small group of paintings framed in silk mats were displayed in 1962 at the Grolier Club in New York. Further showcasing of such artwork corresponded with the international art market's increased interest in Middle Eastern and Persian art during a time when figures such as Empress Farah of Iran became prominent collectors.
The Tahmasp Shahnama, a notable manuscript illustrating the glories of Iranian kingship, received considerable attention and parts of its collection were donated to The Metropolitan Museum of Art. Additionally, paintings were purchased by notable individuals such as Gertrude Stein in Paris where prominent avant-garde figures congregated, and some pieces were showcased in collections like Russian and Soviet paintings 1900-1930 at the Smithsonian Institution's Hirshhorn Museum and Sculpture Garden.
