Diaz Padron accepts a copy from the Brod Gallery and one exhibited Vienna 1935 as genuine, but considers a version that was sold by Sotheby's in 1959 and a piece in the Muller collection to be studio works. All of these are close variants but none, I think, is entirely identical.

A variant by Jan Brueghel the Younger (26.6 x 40.5 cm) combines the flower arrangement here with the vase of flowers from Flowers in a Sculpted Vase Beside a Wreath of Flowers (Gundelfingen). Paris, De Jonckheere, 2002.
