Lot of 4 Robyn Sikking Ceramic Squirrels - Not Hagen Renaker Version!

Description

Listed here is a cute group of squirrels made by Robyn Sikking. These appear extremely similar to the Hagen-Renaker DW squirrels Mrs. and Mr. Chatter, Chit, Chew, etc. but I've been told that these particular squirrels are pieces that Robyn Sikking produced and sold outside of Hagen-Renaker. Under the feet of the two smaller squirrels it appears the name "Robyn" was etched into the clay before the firing process, though it's fairly hard to see. I don't see these markings on the adults.
One of the baby squirrels appears a different color in comparison to the rest of the family - I have no idea in this was caused by different paint or some sort of other environmental factor. The difference looks more aplified in the camera image I took; looking at him through my own eyes, he seems much more similar in color to the others. This particular squirrel has some flecks of white on the body. The white spots are very smooth so I don't believe they are chips, but it doesn't seem like extra paint either. No idea what this is! The adult squirrel with the acorn has small chips on her feet, ear, and a small paint fleck missing on the eye that may appear in the photos as a light reflection rather than a paint chip. The larger adult squirrel looks to be in fantastic condition! The baby squirrel standing up on 2 legs has a few paint chips on the underside of the foot. It's rather hard to notice these chips unless this piece is picked up and examined upside down.
