New travel wall idea

I was scrolling through some mind-numbing social media earlier today and saw this in an ad. I've got my own picture travel wall, but I really love this idea that relates all of the pics to a particular continent/country. At some point, the oldtimers is gonna hit and then I won't be able to recall where/when all of our various travel pics were taken unless I place labels on the back soon. I've pinned these two pics below and will definitely keep this in mind for the second home I'm longing for in the mountains on a lake.
