Most of these turtle paperweights are much smaller. This is the largest version 2.5"x4.25x1" deep. The silvered cast iron has a hinge along the turtle's back and a notch so that the celluloid covering can be lifted up revealing a mirror on its underside and a rather spacious storage compartment within the turtle. Advertising names a business near Philadelphia and reads "Fire Insurance And Real Estate U. Grant Barr Agent For Mutual Of Chester Co./Penn of West Chester." While we've seen a number of the smaller paperweights we've had only about a half a dozen of these featuring the hinged mirror on the back. Exc. and displays Mint.
