Vintage Christian Dior Silk Scarf Ivory Stripes and Birds Monogram

Vintage Christian Dior Silk Scarf Ivory Stripes and Birds Monogram - Measures approximately 26 x 27 inches - I assume that the fabric is silk, but cannot guarantee this as the tag is missing - Scarf is in excellent vintage condition. There is the outline of a rectangular shape in the bottom left corner of the scarf (see photos). I'm not sure what this is. Please see all photos!
