It's either Fenton repro of an early amber thumbprint piece....or a real old thumbprint piece. But because of the thickness of the rim I lean towards the newer Fenton repro.
I think they did a Fenton 1 like that, my mom had the banana bowl, covered tall dish(can't remember what it was called) 1 like pic above & I think a fatter 1 with flat bottom. Seems like she got them from Blue stamps or Green stamps. So they were around 1970's I think when everyone had gold or avocado Fenton!!
