The second overprint commemorated the 40th anniversary of ICAO. The following pictures show the progressive overprints.

Background: Between 1981 and 1989, the majority of Guyana stamps were created by overprints and surcharges that were applied by five different printers located in Georgetown: Government Printer, Bovellĺs Printery, Autoprint, Herald Printing and Tip Torres. Often, one printer would apply the initial overprint, while another subsequently applied the surcharge. As might be expected, given the conditions under which the overprints were applied, some errors exist.
