In my search for oddities, I came upon a small set of "Collect" advertisements. Can you add some more? The first row is a battle between the USA and Australia. USA wins for slightly better centering.
The second row shows that a cancellation, "For the ride of a lifetime, Collect Stamps", looks much better on a stamp with something to do with riding.
The last row is just the leftovers. "Get Stuck into Stamps" is catchy, a little. I prefer "Splash into an Ocean of Fun -- Collect Stamps" which at least lets a sea otter and a dolphin frolic together.
