VINTAGE IVORY/WHITE MINK COLLAR. SCALLOPED, TUXEDO STYLE

Description

My Mother-In-Law gave me this collar back in the 70's.  Don't know what is was attached to--sweater? coat?-- but I
never got around to attaching it to anything!  The snaps are very tiny and it seems well made.
Think it is mink. See last picture for color, seems ivory against the white typing paper.
Approx. Measurements:
The collar:  43" long along inner neckline
The scallops:  4" wide on lining side, the overhanging fur adds a bit more
The tapered pieces: 2 1/2" narrowing to 1" at the tips
There is an approx. 3"x1" discoloration on lining at back of neck.  Perhaps from a label? (See pic. 6)
Hope someone can use this. It's kind of retro cool.
Thanks for looking!
