We rarely find these old glass advertising paperweights anymore, especially in such fine condition.
This one was made to advertise the NATIONAL GLASS SAND CORP. of Millville, N.J. The company produced Glass and Industrial Sands under the name 'Holly Brand'. The company is long gone but they left behind a great slogan...'Clean as a hound's tooth'.
The paperweight of thick glass is imbedded with a glass container of actual sand. These paperweights that contained product 'samples' or inserts are rarer than the standard advertising paperweight.
Measures 4 1/4 by 2 3/4 inches. It's 1 inch thick.
The sand has left a ring around the imbedded sample cup where some grains have spilled out. Overall condition is excellent...no chips to glass, no clouding to mirror. It's a rare old advertising paperweight.
