1917, 2¢ lake, type I. Top margin vertical block of 20, original gum mounted on piece of album page, showing very unusual color transition from the carmine at top to the "Boston" lake at bottom; this NOT due to any toning; contains 10-12 distinct examples of the shade in this block, very dramatic and possibly unique. Scott No. 499h Estimate $500 - 750.
It is worth noting that this came from an old-time Boston collection hidden away for decades.
