Vintage Art Pottery Lily Pad Leaf Flower Frog & Bowl 2 tone Burgundy 17 Holes

Description

Here is a vintage Arts and Crafts pottery flower frog in the shape of a lily pad and matching bowl.  Both 2 tone purple on burgundy.  Purple photographs black.
Frog measures approximately 6 1/2 inches at widest, 3 inches tall.  Frog alone  weighs a hefty 1.5 pounds and has 17 holes.  I regard as  good condition.  Has 1 chip on top edge and 1 chip under glaze, both on left edge near leaf divide.  It is also a little rough along edge.  The purple on the frog has veining.  On hole #4, there is a gray spot under the glaze.
The bottom looks like hand molded and written in pencil "NT/90".
Bowl is matching burgundy on edge, then purple , fading to burgundy,  It is not marked and has 3 white stilt marks on bottom,  If viewed 3 legs on bottom, see the clay matches the leaf flower frog or dirt.  Approx 11 inch in diameter and 3 inch tall.  No damage to bowl.
I am frog collector and had this at least 30 years.  I thought could be Peters and Reed or Haeger or Fulper or ???.
Heavy and big so Mailing USPS Ground.
