Mickey Mouse

I've had these for 40yrs.Can't find anything about them.I think they're for teaching how to draw Mickey.The first one of Mickeys' face is 11 1/16" wide,8 9/16" tall,and 7/8" thick.In upper right corner it says:Mickey Mouse portrait.Below the chin someone penciled in the number 15The second one is 11" wide,8 3/8"tall,and7/8" thick.In the upper right hand corner(Mickey topping his hat) it saysMickey Mouse/action pose.In the center of figures it says:Try your hand at sketching the in-between drawings.Bottom center someone penciled in the number 13.I've talked to many Disney sellers and none of them knew anything about these.
