The left side is a photo of my grandparents circa 1920 -- I believe from before they were married, possibly at Newport Beach. The right side is my DH and YDS, Christmas day, 2011 at Santa Monica.
I used Graphic 45 paper for the background on the left and the two "pin ups" on the right. K & Co "Sea Glass" on the right background. The colors were similar enough, but gave different feels for time periods. I added the more modern umbrella on the left and the older "photos" on the right to embellish each photo(s) with trappings of the other time period.
