An Art Nouveau antique silver mustard pot, complete with original green glass liner. The pot is oval in shape, and has traditional Art Nouveau stylised flowers on the 4 corners, repeated on the lid thumbpiece. The glass pot sits on a circular support, which is also hallmarked (as is the main body and lid). The hallmarks are clear, and include registration mark RD 436134, meaning Walker and Hall registered this design to prevent copying by competitors.
