In year 2012, Belgium, a small country of Europe issued 5 se-tenant stamps on theme of Calligraphy. One stamp shows Hindi script Ek Dusre ko Likhen meaning Write to Each Other. One must appreciate the depth of design and selection of a theme for the stamps. Incidentally this stamp was used by a thoughtful post-crosser from Belgium to Ahmedabad / India with entire tab, which even shows the name of the designer - Dharmesh Jadeja !!
On 11.02.2012, a set of 5 se-tenant stamps was issued by Belgium Post, depicting Latin, Arabic, Chinese, Hindi and Greek scripts. [details taken from MICHEL Katalog]
