Six Cent printings and one of the least common Small Queen varieties.
"The 6c neck flaw is 'A' plate Row 5/1. I got some photostats yesterday of material I think is from the Rixon collection, and it has an off centre copy with a tiny part of the left imprint on which the letter 'A' is just distinguishable. From its position it can only be part of the word 'Montreal'." J. Hillson
