This lanyard looks like one drawn on the cover of Peter Owen's 'The Book of Decorative Knots'.
I tied this simple paracord neck lanyard with a lanyard/diamond knot, multiple overhand sliding knot/scaffold knot, and added a safety break-away clasp with a little needle and thread work.
The lanyard is for my Pa to use to attach to his new cell phone, after his last phone took a trip through the washing machine. I'll add and S-Biner for him to use to clip to the phone...
