Six (6) Antique Limoges Porcelain plates by M. Redon. 

Floral pink rose trimmed banner with floral center. All plates are marked.

The porcelain manufacturer, Marc Eugène Redon, active in Limoges, France from the mid-1800s to early 1900s. 

P L / UNION PORCELAINE: This is likely a decorator or exporter’s mark, possibly from a firm called Union Porcelaine, which worked with various Limoges manufacturers to decorate and distribute porcelain, especially for export markets like the U.S.

The presence of both marks helps date the plates to circa 1890–1910.
