1970 Colgate + MFP Fluoride Dental Cream with Gardol Magazine Ad

This original 9 x 12" magazine ad from 1970 features Colgate toothpaste with fluoride and Gardol.  Did you know that Gardol is trademarked word for a surfactant that Colgate puts in its toothpaste?  If you look back in time this term will be seen in many of their more vintage ads from the Fifties and possibly earlier as well.
