They were given out when large groups were having spaghetti meals for a fund raising event.
Here is an iconic ad: Prince Spaghetti commercial, starring Anthony
UPDATE for February 3, 2016: The mother from the classic Prince pasta commercial has died (click on the link to read article about her death. "Mary Fiumara, the woman who shouted “Anthony! Anthony!” in an iconic Prince pasta commercial, died on February 2 at 88 years old.
The small book, Prince Treasury of Italian Recipes has 305 pages.The above items were used for advertising the Prince Spaghetti Company and Restaurant in Lowell, Massachusetts. The large paper place mats were still given away at the time the plant closed in 1997, 10 years after Borden, Inc. bought them out (my check came from Borden, employees always called it Prince). The bottom two items are much older things from Prince's past. I have a few other items, taken at the time the company closed, which I'll have to dig out and post some day.
UPDATE: I located a pen with Prince advertising, and decided to post here on this page for Prince products.
