Wore out three sets of tires already!
These seem to be very old tube or tire repair kits involving adhesive and heat. I think you must remove the rubber backer and apply to a cleaned patch spot and also apply heat to the asbestos backside without you, your tube or your garage bursting into flames. Cool display items. Not recommended for starting fires.
Thanks to the Cabers who ID these for me!
