OOAK(?) Sitting Rabbit Doll (1992) - Used Condition

Description

Hello! This is a
(possibly one of a kind) cute rabbit doll made in 1992
. This is a thrift store rescue so its history is unknown to me. I cannot find anything about it online and the signature suggests it was handmade, so I am guessing it is OOAK.
It is mostly fabric except for the pine cones (or perhaps they are carrots?), which are made of some hard material.
Since it came from a thrift store but doesn't appear to be washer-safe, I sprayed the doll down with Tide Antibacterial Fabric Spray just in case. There is some small staining on the left foot, as shown in the photographs. The fabric looks yellow-ish as if aged; I think that is just its natural, intended color...but again, I can't be sure since I know nothing about this doll.
There is a signature on the back of the right leg, but I cannot read what the cursive letters say. My best guess is 'Der'? It is followed by a 92, which I am assuming is the year it was made.
Please note: the item comes from a non-smoking, cat-friendly home.
If you have any questions, please feel free to contact me.
