| /Broad C in Centavos Escudito with no accent on U variety, showing the partially worn plate. Pretty blue, mute cancel with stars in rhomboid design. Proven to belong to Gualeguaychu, although attributed by Kneitschel and Solari to Parana.
| /Paper fold error with partial printing on the gummed side of the sheet due to a corner fold. Marginal block. Small paper tear in selvedge only at left. Top two stamps LM Mint, bottom two MNH.
| /Uncatalogued in Scott but listed as 457a-462a in Cefilco. No 1.40 Bs. One stamp MNH, the other LM Mint.
| /An obligatory surtax applied to aid in the construction of the new Post & Telegraphs building. ABNC die proofs in the issued colors, on India paper, mounted to cream stock card.
| /Very undercatalogued in Scott, about right in SG, the Costa Rica SCADTA stamps were handstamped in very low numbers (ignore the image in Scott which shows a false machine cancel - the Costa Rica overprints were all handstamped, except the 30c which was also machine stamped in Berlin). There were only 75 overprints of the 60c and just 50 examples of the 1 peso. Two shades of the 30c value are included in this short set.
| /A dark ultramarine shade, clear impression with complete 8th November 1867 Alausi cancel. An elusive cancellation.
| /An early franking from 1875 on piece. Particularly desirable as this red cancellation was only used in Quito for a short period of time.
| /Waterlow intermediate die proof for the 20c value, omitting the vignette of Rooseveldt. Die number handwritten in upper left corner, cylinder number in upper right and proof number in lower left. Includes two MNH blocks of file copy proofs of the finished stamp with punch holes and "checked for colour" notation in the selvedge, dated five months before the stamps went on sale. Unique.
| /Full sheet with file number (487) and Waterlow imprint to base. Provides a clear visualisation of the plate format and the five types, plus all the listed flaws. A small amount of separation.
| /ABNC proof depicting Worker's Housing. Die proof in the issued color on India paper, sunk on to cream stock card. A few minor tone spots.
| /Front cover/wrapper dated Callao 21st April 1856 with decorative boxed Franca hand stamp in blue. Truncated to both sides.
| /Three ABNC die proofs from the 1918 series of stamps, comprising: I) 2c Green on India paper mounted to cream stock card, further mounted with acetate protective cover II) 4c Lake sunken die proof on India paper mounted to card III) 12c Dull Violet on India paper mounted to card. A few light surface stains and paper abrasion to left and right guide marks where clamped in place.
| /One of the two major flaws in the sheet. Position 68, showing either a retouch or damage around the EG of FUEGO. Unmounted block of four showing the flaw on the upper-left stamp.
| /One of five values (7c, 10c, 20c, 25c, 1p) overprinted without authorisation by postal workers. The stamps were not generally released but saw postal use (see note after Michel 49, Officials section). See also note in Scott after O60.
| /A full set of the Artigas / Commercial Progress allegory issue. Ex Waterlow archive file copies in blocks of four with security punch. No gum with residual water staining; a result of the flooding of the London archive, held in the basement of the printer's premises, during the German bombing of London in WWII.
| /Four margin, genuine stamp with a pretty but highly suspect star cancel. The stamp was a reduced rate value, used for posting newspapers.
