Choose a title for your talk. The name of the event should directly reflect the main focus of the information you wish to share while enticing potential guests with creative language. "Thinking Outside the Frame" and "Impressions of Youth in Prussia" suggest an artist's talk on inspiration and process more than "The Business of Creative Design," which would imply a talk on money matters and marketing strategies.
Have the "where" and "when" of your event in bold, clean letters, set apart from the rest of the type, where it is visible at a quick glance. This information should include the location, the date, the time the event starts and the time it will end.
Give a brief description of the ideas you intend to share with your audience. Mention your area of knowledge and tell your guests how it applies to the talk you're giving, and how they can use it to enrich their own experience in the arts.
Is it an "invite only" event? Do you need an RSVP? Be clear on whether or not the location for the artist talk can accommodate walk-ins and extra guests. If it is reserved seating or a guest list, you must mention this clearly on the invitation.
Highlight any important information that will pertain to your audience's coming and going to the event. Include: prices per ticket, how to order tickets, websites and contact information for the artist and the event center. Consider giving driving directions and parking instructions. Your guests will thank you later.
If your invitation is in a small, mailable format, such as a postcard, an A7 size or smaller, then you may only have room for the above information. If you're printing a brochure or flyer paper, or advertising your artist's talk on a website, you have a little more room to add an artist's statement. Consider writing a brief bio and statement on why art inspires you, or how you choose to use art as a form of expression. This will give your potential audience an introduction to the person behind the art, to get them excited about what you have to say.
