In the world of stamps, you sometimes see overprinted stamps. This is where the country has taken a previously issued stamp and altered it to celebrate an event. This stamp shows the Coralita, or coral vine, a colourful flower from Mexico that is common in the Caribbean and Bermuda. The stamp has been overprinted with 'HEATH-NIXON DECEMBER 1972'. This refers to a summit between the two leaders where the US President voiced concerns about trade after Britain joins the European Union. If only they knew what 2020 would have in store!
