Description

Photos in order are:  Two together, Two together, Plate, Plate, Plate back, Bowl, Bowl back.  Plate is 8" and bowl is 6" and about 1.5" deep.
These were my grandfather Reggie's "bachelor" dishes from when he worked for Imperial Chemical of England, and lived in Japan and China and Singapore from about 1915 to 1950.  He was a bachelor until he married his best friend's widow, my grandmother, in the mid 1950s.  These were his dishes.  They are very lightly used because he was a bachelor!  He left behind 4 bowls and 8 plates.  These are the first two. One of each.  Looks like a dragon to me!
My research says these are most likely Quing dynasty, and my grandmother always had the impression they were old when Reggie bought them in China in the 1920s or 30s.  She gave them to my mother when Reggie died in 1984 or 1985, and they've been boxed ever since.  I expect the dynasty mark is an honorific, not a genuine date.  The mark on them is not Quing, but something else and I am too ignorant to decipher it or recognize it.  Collectors will know best. The mark on the plate is easier to read.  They are both (all) underglaze marks.
The bowl is not a rice bowl or a teacup.  (My father was raised in Japan, so I have a TEENY bit of knowledge and know a rice bowl when I see one!)  They may be made for export, but generally there are NO marks on export pieces, so I'm just guessing based on the style of the bowl.
