Vintage Fabric Panels

My husband often talks about his "Daddy Bear", "Momma Bear", and "Baby Bear" he had when he was a child. They were sewn from fabric panels, so they were just stuffed, like pillows, but were bears. There was a quilt that matched.

When I met him, we found the quilt at his mom's place, along with the Momma Bear. Unfortunately, both were lost due to mold when our washer exploded one weekend. That was about 10 years ago.

The other day, I went to Goodwill, and sitting there was the Momma bear, and what I presumed to be the matching Daddy bear (it was). Now, I'm trying to hunt down the actual fabric panels, because these two are falling apart. I meant to keep them for Christmas, but I was too excited, and showed him. Shoulda seen the
look on his face, though! Anyway.. I've tried ebay, but have had no luck. I don't know what the actual fabric would have been called, though, so I'm not sure if I was searching the right phrase up. I tried "3/three little bears" and "3/three bears", etc, to no avail.

Does anyone know of any websites that specialize in vintage fabric panels? I would assume based on Nick's age, and the colors in the panels, that they are from the mid 70's, maybe a bit earlier.  Nick apparently went through several of them growing up. He remembers even helping his Grandma sew the last set he had.
