A couple decades too early for Post-Its.

I was going to say they were a double note attempt by me (my address on them) to get the rifles shipped to me.  Trouble is, the women were delivering the packages ten years before I was born.  –I always miss out on the good finds!

Definite “security measure.”  Those Post-Its appear to be extra tape, probably across the box bottoms and up the other side.  The tape looks to have been snagged or cut on some boxes. 

Women of gentle beauty.
