TDI are regular client of mine and I have been working with the client for a number of years. This is an example of their exhibition banner.
TDI have a number of services including Disc-check. There was a series of 6 pull up banners they use for exhibition trade shows, some smaller local events and training courses for each of the main services they provide.
TDI have had a number of larger exhibition stands for the annual event at the NEC.
