GCGEPU-173 Undated Advertisement for Ovaltine Gil Elvgren (1914-1980)

The picture has something of this: people, woman, wear, dress, veil, dancing, portrait, two, jewelry, princess, music, flower, facial expression, flower arrangement, retro.
Perhaps it’s a painting of a woman in a red dress standing in front of a bed with flowers in the foreground and a green door in the background.
