Accumulation, 1851-1932, four items: a very fine appearing no. 15 (with an 'imaginary' trivial corner crease), an extremely fine no. O81 with blue cancel (which we feel is the soft paper no. O112), an otherwise extremely fine mint no. C13 (has single short perf.) and an unused block of four of no. 716 (the so-called 'varnish-ink' variety, but the P.F. is unwilling to certify it as such), nonetheless a very spectacular printing freak, otherwise very fine-extremely fine lot, nos. 15 and O81 with 1997 P.F. certificates, Scott retail $643.00+
