The M.T. Abraham Foundation is a non-profit cultural institution, which is part of the Israeli M.T. Abraham Group. Its headquarters are in Tel Aviv, Israel, and its part of the collection is on permanent display in Mostar. Its stated intent is to promote public appreciation of the most important styles of Modernism: Post-Impressionism, Fauvism, Cubism, Cubo-Futurism, Futurism, Constructivism and Suprematism by collecting pieces that can be loaned "for the sole purpose of display and study by public institutions," and to present most effectively the first half of the 20th century, a period that saw revolutionary tendencies shape the art scene.

Aleksandra Aleksandrovna Ekster, also known as Alexandra Exter, was a Russian and French painter and designer.
