In our paper, these two pages are the only pages which can support full color pictures. It is a compliment to be on the back page, in reality. That is why the back page is designated for Sports. At the Postal Service, we do not refer to any class or type of mail as junk. All mail is important.
Mail is broken down into different classes.
There is Express Mail, Priority Mail, 1st Class Mail, Standard Mail, and Periodicals. A 1st class letter might be a Social Security check, a letter from a loved one, a Christmas card from an old friend, a bill or payment, or maybe a contract on the sale of a house, and is obviously important to both the sender and the receiver. If it weren t profitable to do so, companies would not waste their money sending it. Obviously it is important to the customer also because many people order from these advertisements. Periodicals, such as your newspaper or many of the magazines, are important to the sender because they provide an income for the person who sends them, as well as to the people who have paid for advertisement in these in these publications.
