Physical description

A plain, rectangular adhesive sign (with rounded corners) with the logo of the PTC printed in front. The brand of the adhesive (3M Controltac) is printed on the adhesive-covering paper on the reverse side. The logo is printed via applying pressure to the label; it is likely that the original adhesive film (which would be made of plastic) has been used.
