This set is to commemorate the significant milestone of the 50th anniversary of Singapore and India’s bilateral relationship.
Joint issues by postal administrations are very popular nowadays, both for the issuing bodies and collectors.
Collectors from both the countries want a set of the the stamps from each country. This means extra sales and profits for the issuing post offices.
No wonder more and more are being issued and usually under the guise of cutual exchange of to improve country to country relations.
Anyway, Singaporeans are known to be eating out a lot but I am not sure whether this set will appeal to non collectors.
