Calendars are everywhere, both home and office. In businesses, they are often on the wall right next to your desk, or in homes they are often on the fridge. This provides a unique opportunity to use calendars as a promotional product. Displayed with your logo and contact info, they are in view all year long as a constant remider of your companies products and services.
Desk and wall calendars are large enough that other prospects visiting your client will also see your advertising, and may prompt them to ask the client about your company! A calendar is your opportunity to be in front of your customer or prospect when they need to call you. A calendar will stay up in an office or home for 365 days, so your chances to get a phone call from your customer or prospect are pretty good.
