The Jamaica 6d abolition of slavery postage stamp was prepared for issue in June 1921 but cancelled shortly before issue due to political unrest and the controversial subject matter.

The first two consignments arrived in Jamaica around the same time, and were incinerated at the General Penitentiary in Kingston on July 2, 1921.

The final consignment, arriving in October, was similarly destroyed.

This block mysteriously disappeared from the Post Office's vaults[when?]

[1] As the stamp was so close to being issued, specimens were sent to the Universal Postal Union as usual, a number of which survive.
