Three signed Japanese cups

Each of these cups is about 3.5" high x 2.5" in diameter. All three are hand made, hand decorated and marked with a kiln or artist mark. All three are extremely high quality.

I found these three random cups together in an offering of a bunch of completely unrelated stuff, nothing else was Japanese.

The first cup is deceptively simple looking, but has several features of a well decorated cup, brown coloring around the upper rim and inside and outside of the lower rim of the base, a blue ring around the inside of the rim and a matching blue band on the base, a black line between each major color band on the exterior. Unfortunately, the kiln marking is too illegible to attribute.

The second cup has a heavy glaze which varies in thickness between the various bands of colors. The base was left un-glazed and the bottom is beveled. Though pretty well defined, I cannot make out the kiln or artist mark, or determine the correct orientation for reading it.

The third cup has, I think, a generic Kutani mark. It is decorated completely around the cup with two red and two white flowers.

The interiors of all three cups are white or off white, so that the drinker can observe the color of the tea in the cup.

I get the feeling that these three cups came from the same owner though are not made by the same kiln or perhaps even in a common time frame. Three very nice cups for only $5 and tax.

Please excuse my somewhat slapdash image editing.
