Vintage Double Mushroom Ceramic Hat Pin Holder Yellow & Brown Tones Beautiful

From a smoke free home, very pretty with no chips or cracks though has some crazing from age. With a beautiful glossy finish this would be nice for the intended purpose of a hat pin holder or just as nice on display with other mushroom pieces. I have added pictures with the dimensions. There is a mark on the bottom but I can not make out what it says. My guess would be that this is from the 1960's but I could be off a bit.
