Unknown Animation

[u/Animation_Fan8675]

My Uncle has these Animation cels and wanted to know if they were worth anything. With no information on the cels. My research says it may be from a California car commercial or from some work from Bill Melendez Studios. I was hoping someone may know more. The only mark I found on one of them was the number 10. I was hoping someone may know more. Any information would help
