A Cover from Singapore

Below is a nice cover from Singapore. Two 1st class stamps (commemorate the Youth Olympic Games held in Singapore) are used to send this cover. I am not sure if the postage rate is correct. I would be highly delighted if the correct postage rate is employed on the letter/cover. Anyway, this cover is cancelled with a beautiful slogan postmark commemorating the Youth Olympic Games held in Singapore on August 14-26, 2010. The postmark was dated on August 16, 2010.
