The specific name of this artwork by Joan Miró is "Le diamant sourit au crépuscule" (which translates to "The Diamond Smiles at Twilight").

Miró painted this oil on canvas in 1947. The original piece measures 97 x 130 cm and is on loan to the Fundació Joan Miró in Barcelona, Spain (which is why your specific gallery print likely carried the "Fundacion" label).

The painting is a classic example of his surrealist iconography, featuring the "diamond" (the checkerboard kite) soaring in a dreamlike twilight alongside celestial bodies like the moon, a red sun, and a glowing blue face.
