Lottery Win - Joanna from Switzerland

This is from another lottery I was lucky enough to win in the summer. This metal postcard was being offered by Joanna. It features an advertising for Coca-Cola. I have always preferred Coke so for me it was a no-brainer to try and win it. Because it was metal she was sending in an envelope which I totally understand. I am glad she translated the back for me as I probably would of thought is said "affix stamp here". I had a good chuckle when I read "Please send in an envelope" and I agree with her - why add the address lines? Who knows! This is my first metal card.
