Keepsakes for buyers and media are a good idea but bigger is not always better. Other than a postcard or marketing kit flyer, if you have cool buttons or pins that are designed and include your URL on them these tend to create a viral marketing buzz.

It’s amazing what you can achieve within an 8′ by 10′ space which is often the minimum size of a trade show booth. Make the most it of it with proper signage of your brand’s logo, a carefully displayed rack of your collection -often on at least two sides of the booth area, a portfolio with any media you’ve been in from magazines or online magazines, and leave-behind material for either buyers glancing in your direction or media that may pass by.
