Vintage Butterfly Bed Sheet, Twin Flat Top, Hanae Mori Butterflies and Leaves P

This is a vintage twin size flat sheet with a whimsical butterfly print and tree print designed by Hanae Mori. The background is cream white. The leaves are printed in sage green and and the butterflies are printed in coral orange. There is a unique lattice pattern stitched into the hem, along with a piping stripe of coral orange. The edge of the hem is serged. The tag has faded and is no longer legible, so I am unsure of the fabric content, although it feels like a 50/50 cotton poly blend. Unknown maker, unknown pattern name. Measurements: Twin size, 64 1/2" wide x 94 1/2" long Condition: Very good condition with no flaws or damage. Tags have faded and are not legible.
