Colombia SCADTA 1923 Costa Rica Airmail Overprints Top Values MNH. Scott CLCR9-CLCR11

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 50 overprints of the  2, 3 and 5 peso high values.
