Final answer:
Georgia O'Keeffe's paintings regained popularity in the 1960s and 1970s due to their abstraction and self-expression, aligning with contemporary tastes, and the feminist movement's rediscovery of her significance as a pioneering female artist.
Step-by-step explanation:
The resurgence of popularity in Georgia O'Keeffe's paintings during the 1960s and 1970s can be ascribed to multiple factors. Firstly, her large-scale, abstracted paintings of flowers and New Mexico landscapes responded to a cultural shift towards self-expression and abstraction, aligning with contemporary tastes. Secondly, the era's dynamic and experimental artistic scene brought a renewed interest in artists who challenged traditional conventions, which O'Keeffe was known for through her work. Moreover, O'Keeffe's life and work had a resurgence of scholarly and public attention, thanks to the feminist movement which recognized and celebrated her contributions as a pioneering female artist in a male-dominated field. All these elements, combined with the fact that her art provided a perfect match for modern home aesthetics, contributed to her renewed popularity.
