Coordinator notes: NW Frit male...you can't see the eyes in these photos but in the field they are blue-gray. The Aphrodite has amber or brown eyes but sometimes depending on camera angle they will look that color on the NW so photos can sometimes be deceiving. The spots on the underside here you can see have no silvering. They are always silvered on the Aphrodite...a rarity if unsilvered. Mike
