Seems from comparison online to be Duncan Miller chalkware bathroom wall decor. In aqua and white with bright red lips. Mama fish is about 9 x 6.5 x .5 thick. Baby 3.5 x 2.5 x .5. In great condition for their age: See 2 spots of white in the tail of Mama fish and one spot of white in the top fin of Baby fish. One hook intact on each plaque. The bigger fish has holes on the back that might have held other hooks. Fish have not been displayed for at least 30 years.
