Sterling silver bookmark-Heart within a heart. Marked Napier sterling. Mono of EKB on center heart-passes for a design. 
Dated 10-21-50, ask EKB. The heart in heart is what you see with scrollwork between.
Napier Sterling 1920-99, Meriden CT. This piece would be from uhhm, 1950? Educated guess. Anything 5 years older than me should have antique status so bid that way.
