Antique White Ironstone Relish Dish.

9" x 5" x 1.25".

Marked: AM...   That's all I can make out.  If you know the maker, please share!

There is a tight, fine hairline on the bottom right side where there a light stain line.  There's some minor use wear to the glaze on the rim.  No chips.  

Very unusual decoration - a human head or face.  A different and lovely piece!
