Help with spongeware ID

[kurt49]

Looking for any info on this spongeware. The pieces are small with the pitcher being 5" tall (7" to top ball of lid) and the other pieces are 2.5-3.5" tall. 

They are each marked with a small black (Japanese??) mark. Each mark is different on each of the pieces..

I don’t know the maker but the mark looks like the letters A and K, rather than a symbol or Japanese character.

Could be Marshall Pottery Marshall TX

Given the size, is it possible they're meant for children?

That's exactly what I was thinking. There is an identical pitcher on ebay by Marshall Pottery and the craftsmen and women were known to incise or sign in ink. However,Marshall is always marked on the bottom. They are out of business but a few others still in Marshall Texas making nice pottery.
