on my easel each is 16x20 Oil on canvas

The idea for this "triptych" has been percolating in my mind for some time.. It (they) are not finished, but almost. I am unsure as to marketing them as a trio or individually. I intend to put a resin on each one when I am done. I am also unsure as to signing them, because they can be placed in various positions. Advice is welcome. All of the Navaho Daydreams paintings are currently showing at the Dutch Art Gallery.There is now only one left of this tryptic.
