From the reference box #47
#47 - a Swiss letterhead from the 60's. I'm terrible at languages but I think the letter is in German and I'm pretty sure the 'V+S' is a tourist board logo. However I could be totally wrong, so if you have any info please get in touch.
I found it nestled amongst some bits of ephemera I bought a few weeks ago and really loved the logo, it's such a funny choice of typeface for such an official looking letter, but I think it's great. I especially like how the '+' has been reversed out of the 'V' to create the national flag - simple but effective!
