Corinphila Auction 284-290 Day 3

1872: 1 r. yellow on quadrille paper, a vertical strip of seven with large margins all round with fifth stamp just touched at left, but with seventh stamp showing the embossed "Arms of Ecuador" security seal (unlisted by Scott on this stamp); cancelled by seven strikes of the "Ambato" datestamp (June 20) in black. A few trivial imperfections but a rare and attractive multiple.
