A lovely, unusual pattern for Haviland. The bigger Square plate measures 5 1/8 x 5 and 1/8". the butter-pat measures 3 x 3". Both are marked. They do not have the same markings. H & C, Small zero underline and a L, that says Haviland and co, limoge: the butter pat. The larger plate is marked Haviland and Co, four. Wright Tyndale & Van Roden, Philadelphia. it also has the H & C Small little o, underline with the L. I love when I run across these Haviland plates that were created for department stores. Both units are perfect.
