Ghirardelli Vintage Advertising Card for Rocky Road, Milk Chocolate Sundae Sauce, & Milk Chocolate Icing

I was at the Flea Market a few weeks ago and came across this Vintage Advertising Card for Ghirardelli Milk Chocolate. I'm not sure if it was included in a packet of Chocolate or just an advertising piece. The quantity says 14 ounce net wt., so I'm thinking with a large Baking Bar? I love that the card says "Gear-Ar-Delly"... always good to pronounce this San Francisco landmark correctly. No indication of date, but 'table cream' is a clue. I would think 1930s, based on other recipes from that period.
