Skeletal Feline Cut and Hinged Mask
These heads are all bone colored, and can be stained to give them a weathered look once you've washed them off with soap and water.
Fits up to a 24" head, and will work with glasses.
No jawset/tongue/eyes needed. This head will fit all tongues except point/forked dragon, horse, point/forked sergal, rat or deer. Bunny and fox look odd, because they are small.
A 1" or 7/8" Fan will fit if you remove the nasal cavity, however it has excellent ventilation so a fan isn't really necessary.

To finish it off, you can use some speaker cloth to cover the eye ports: https://dreamvision-creations.myshopify.com/products/speaker-cloth-for-skull-blanks
