A few thoughts, as I wait for Spiderman to rescue Gwenn:
- There are plenty of websites that will allow you to date that postcard back. If it passes and is early 1960's...
- ..and if so, it's almost certainly a real photo, but easy enough to check.
- The borders certainly don't preclude it being 1960's - that was common for 1950's also.
- When in doubt, I always ask myself, "would anyone have incentive to fake such an item?" In this case, the answer would almost certainly be "no"
