Freebie Alert: Singapore Medicine Postcards with prepaid international postage

I came across another free-postcard promotion recently when I was at the post office. This series of 5 postcards promotes the medical facilities in Singapore.

My one quibble: they could have made the postcards more attractive. Looks like most of the pictures were originally taken or created for a brochure. I would have liked to see much more creative postcards. The type which will make people WANT to send these cards to their relatives and friends. As it is, to my eyes, only the one on the far right is attractive. And my second choice would be the one second from left in the picture above. At least that has some conceptual interest. The rest...

There's no lucky draw for sending these cards, just free overseas postage. The plus point: it doesn't look like there's a post-by date attached to this set.
