This stamp was on the page with the "dry impression" stamps I posted in another thread.
This stamp does not show the same upon closer inspection. It doesn't have the absence of color that describes a dry impression.
I wonder if this is a "slip print" example?
There is a blurring at the edges of Washington's face. Also you can see it in the close up image along the right frame line and medallion.
Sorry for the poor images.
