Vintage Russian Frog Princess Palekh Hand Painted Trinket Box

Vintage Russian Palekh trinket box. Beautifully hand painted with black background, and red interior. It has a hand painted traditional scene on the front of a frog princess sitting on a leaf, next to a prince. It has metallic gold floral scroll around the outside of the scene, and around the edges of the box. It's signed underneath the picture, but I can't tell what it says. Unique gift, and fun collectible!
