This is a lot of two Japanese ambrotypes from the Meiji Period that appear to be of husband and wives, probably from the same family. It is quite evident that both photographs were taken in the same studio and probably on the same day. All are wearing the traditional grab, but each man is wearing a bowler hat. What I find interesting is that in one photo the man is sitting and holding an umbrella. In the other photograph the woman is sitting. There is some Kanji script on back of the case written is a white ink or crayon that is very difficult to distinguish. There are some condition issues with the photographs.
One ambrotype comes in a handcrafted polonia or kiri wood case (Berg 6-138, VR p. 460) that is missing the top. The other is without a case. Both images measures 2.6 x 3.6 inches and the case is 3.25 x 4.375 inches. With the exception of the missing lid, the case is in very good condition.
