Georgene Novelties 1948 Alvin doll from Little Lulu. Doll has held up pretty well for over 70 years old! As you can see in the pictures there are no loose threads except for the shirt button on back. 

The pants are a khaki color with blue staining, but I believe the pants used to be completely blue but the color has faded away. 

There is no odor. From a smoke-free home. 

Sold as is. An antique item with signs of age.
