If your "Large Pin Curls" need holding...here are the clips for you.
A sheet of 5 clips, 6cm long,  on their original 1940s display card
"Lady Ellen Hollywood Klippies" 
and a charming picture of the 1940s Allied Artists star Elyse Knox showing you how to clip the curls.
They were packaged by THE KAYNAR company in the USA.
I have 3 cards and they are all a little creased.
On the backs of the cards are the other clips in the Lady Ellen range.
