From the time of the 'Tulip Mania' in the 1630s, depictions such as these of individual specimens of tulip were immensely popular, and the prototypes from earlier 'tulip books' were repeated over and over.  The paper used in the present examples suggests that they, like the closely related sheets in the Christoph Müller Collection, were executed circa 1660.¹
