The decoration of the garden urns is a strange mix of fantasy and reality. The cherubs are probably intended to be statues, the ornament on the upper rim would be appear to be in the form a an ovolo moulding. The shape of the vase is the same as the urns in the Dyrham Park collection, all attributed to De Grieksche A. The decoration is somewhat reminiscent of a wall fountain with basin in the Prinsenhof in Delft.
A pair of vases of the same form but with different details is in the collection at Schloss Rohrau in Austria.
