Finally figured it out.
I've always loved combinations of Bocote and Wenge for custom bow creations. The rich grain of the bacote, the chocolate and copper hues of the two woods just seem to compliment each other nicely.
I had Brian Wessel build the bow in the pic for me 4 or 5 years ago and love the bow. My Tall Tines has darkened over time but when it was new it resembled the pot call in the pic.
I was rigging up a strutting decoy with a wild turkey fan and my bow was a few feet away, when it dawned on me that maybe my fascination with bocote and wenge was due to the similarity of colors and patterns found in the tail fan of North America's greatest game bird.
