Vintage Red & white ceramic block Salt & Pepper Set milk glass

Salt and Pepper set from an estate - remind me of 40s or 50s block sets White milk glass with red plastic tops, unmarked about 3.5 inches tall, 1 3/4 wide Plastic tops turn to allow pouring or shaking, P top is cracked on side but still works, its just a little loose and you need to be careful when taking it on and off. Doesn't leak or anything. overall really cool vintage set
