The Talking View-Master by gaf is a piece of vintage entertainment history! The Scooby Doo reels are included with the view-master, but the talking feature does not appear to work. 

Dimensions: L 6-1/2" x W 5-1/2" x H 9" 

Condition: Wear on boxes consistent with age, and we were not able to get the integrated audio feature to work.
