Harmer, Rooke and Co. of N.Y.
24c carmine rose and blue INVERTED CENTER. Beautiful, bright fresh copy. Extremely well centered and very fine, o. g. Only a handful of copies in such fine condition are available to collectors and they are rarely offered. Two copies similar to this have sold at auction for over $4000.00 each. Probably the most famous of all U.S. stamps and worth at least full catalogue. (See photo)
