VERY FINE. A RARE PAIR WITH TOP STAMP THE "CANAL" ONLY VARIETY AND BOTTOM STAMP "ZONE CANAL". ONLY 20 SUCH PAIRS WERE PRINTED.
This error was caused by a downward shift of the overprint, leaving the top 20 stamps with "Canal" only and the bottom 80 with "Zone Canal". Only 20 such pairs were printed, however, some have been split up, leaving fewer se-tenant error pairs available. (Image)
FINE. A VISUALLY STRIKING BLOCK OF THE 1926 5-CENT WITH INVERTED OVERPRINT. ONE OF THE MOST IMPRESSIVE OVERPRINT ERROR PIECES OF THIS ISSUE.
According to Canal Zone Stamps, these errors were created because the press was set up as a 100-subject overprint form to accommodate narrow selvage at bottom. When one pane was mistakenly placed on the press in an inverted orientation, the top row missed receiving the overprint, which was printed instead on the wide selvage at bottom. This bottom-margin block of inverts shows the misplaced impressions in the selvage. The pair in the following lot shows the missing overprint on the top row.

VERY FINE EXAMPLE OF THIS DRAMATIC ERROR. ONLY TEN PAIRS ARE POSSIBLE.
According to Canal Zone Stamps, these errors were created because the press was set up as a 100-subject overprint form to accommodate narrow selvage at bottom. When one pane was mistakenly placed on the press in an inverted orientation, the top row missed receiving the overprint, which was printed instead on the wide selvage at bottom. The block in the previous lot shows the effect at the bottom of the same sheet. (Image)
