Demo for using Snapseed Double Exposure

I thought that I was using a camera club architecture image to demonstrate creating multi exposure images in Snapseed.  I found out yesterday, on our trip to York, that the architecture image actually came from a set of images rejected by The Master of Prints exhibition. The photograph of the image was a bit skewed in the frame, but it quite surprised me that it wasn’t accepted.  I needed something simple for the demo, so used the symmetrical architecture image overlayed by the blue and white simple blue and white image that I took when waiting for my X-ray.
