When selling guitars at school, you have to write leaflets. How to write better?

The beginning must be novel, so that people will want to see what is written on the leaflet from far away.

For example, the title is "bad news" and then enter the main structure you want to say below. You can add some popular jokes to express your intention and advantages in selling guitars (for example, the dialogue ps between Fiona Fang and Di Renjie is out of date, and the friends are stunned). Finally, write a contact information. That's O. promote this thing, and attract people's attention ~ try to adopt it with pure hands ~
