Lot 40081 – 1866, 100r green, type I, die I, on 1st April 1867

1866, 100r green, type I, die I, on back of 1st April 1867 cover from Pará to Maranhão, tied by “Grampará” octagonal postmark (Ayres 1311); several faults caused by tropical weather conditions and cover edge reinforcements, still though an extremely rare usage of this pre-adhesive postmark on “Dom Pedro” cover (a cancellation mostly found on “Bull’s Eeyes”, issued more than 40 years before).
