EXTREMELY FINE. A BEAUTIFUL AND RARE BOTTOM DOUBLE PLATE NO. BLOCK OF 10 OF THE 5-CENT PAN-AMERICAN ISSUE.

Bottom plate blocks of ten are more desirable, because they show plate numbers from both the vignette and frame plates. A Power Search review found only a few other examples offered in our sales in the last 25 years.
