Lalique designed a small number of variants on the winter landscape theme. A near identical version of the present pendant is in the collection of the Calouste Gulbenkian Museum, Lisbon. The museum records confirm that it was acquired by Gulbenkian, Lalique's greatest patron, in 1900. The museum also owns the original design executed in pencil, ink and gouache.
