Antique Cameo Portrait Plate Set of 3 CT Altwasser Germany Victorian Woman

Set of 3 antique porcelain (1890-1914) C.T. Altwasser Germany marked plates. The edge design is colorful flowers with gold accented leaves/vines in between. The middle of the plate has a Victorian woman portrait. I believe the portrait was placed there after the fact by whomever bought these due to the fact the portrait is signed MINOR or MINOX at the bottom, and none of the other plates of this same maker have a signature by the photo in the middle. The back of the plates are all stamped with the plain green bird and "CT", "GERMANY" in green, and have a set of different production numbers written on each one, similar to 20 451 46. Plates are 6 3/4" around and almost 1" tall. There's an additional plate that is cracked and re-glued on the edge that i will include, at no cost, if u want it. The 3 plates are in great shape. Smoke free home.
