Lot 369, Canada #387a St. Lawrence Seaway invert block of four

The premiere item in Sale #4 reached a hammer of $44,000. In response to the many who asked, yes, it’s staying in Canada.

Canada #387a, St. Lawrence Seaway invert block of four. The great Canadian error.  The block has a fingerprint on the gum of the upper left stamp and traces of a light fingerprint on lower left and upper right stamps (as seen with "Canada" upright). These are not uncommon for the Seaway stamps, which were identified in the regular stamp market and handled, however gently, by non-collectors at that time. Unitrade CV $64,000, realized $44,000.
