Each image consists of a small original image, outlined in green, and one or two larger images that are outlined in white. In each instance, the larger image is a combination of one part of the original (mostly one half) plus that same part flipped horizontally, to make a symmetrical image.
In a different album I have included about 165 symmetrical images, composed in the same way, but without including the source images. Click on Symmetricals 2022 to view the album.
