rare Holly Hobbie print fabric, girls w/ giant mushrooms Manes American Greetings

Rare vintage Holly Hobbie print fabric, girls with giant magic mushrooms! I've never seen this design before.

It's a quilting or dress weight cotton fabric, selvage marked Manes / American Greetings. This is 44" or 45" wide, 2 yards.

There's a faint print flaw across the width of the fabric, a manufacturing flaw. Otherwise nice, crisp, never laundered. Colors bright without fading.
