A services firm at a business expo is selling credibility, and credibility at a trade show means client logos. Printed, they fill a board and date the moment a new client signs.
DSD built screens into the stand so the client wall runs on rotation, alongside case content and service messaging. Adding a logo is a file, not a reprint.
It also gives a small stand more surface than it physically has — the same square metre carries four messages instead of one.
