Among these
First Printing stamps, at least six sheets with the red frames had been inadvertently turned 180 degrees before being placed in the press. So, although the heads appear to be upside down, it was the red frames that were inverted. D.N. Jatia found that at least six sheets must have been fed into the press upside-down, as six of these stamps from Position 4 showed different lithographic stones were used for the head and frame dies. The surviving examples of this error are low in number.
E. A. Smythies states that, at one time, "Details and illustrations of all the known copies [were] given in that interesting publication,
Stamps of Fame, by L. N. and M. Williams." One additional example has been reported, yielding 28 total known examples. All of these are postally used. Only two (or three) are known cut square; another 25 are
cut to shape (that is, in an octagonal shape). One from the collection of the Earl of Crawford was exhibited in the World Philatelic Exhibition in Washington in 2006. == Discovery of the error ==
