Here's a sample of the stamp:
(Not one of mine)

The stamp has a distinct 'old west' flavor.
Everything from the dark brown ink, to the
beads around the portait, and most significantly
the old west sheriff's badge style star around
the 5c denonination. It smacks of 1882 poker
games in the saloon to me. Probably the only
contemporary stamp that does so IMO.
