Blue-Gray Small Pottery Slab Plate with Incised Stripes and Pale Brown Loop

Just a perfect little plate, which strikes me every time I look at it.  It feels very Zen to me--a completely harmonious balance of form, texture color and gesture. I might use it for a little treat to go along with a cup of tea, then for the tea bag, too.

Signed on the bottom but I can't make it out. 5 7/8" diameter x 3/4" tall. Very good condition. The unglazed edge is a bit irregular, possibly with a couple of very tiny chips but if so super minor.
