Hewlett Packard Australia recently took to the streets of Melbourne, Sydney and Brisbane for the HP Beats Sound Challengeā„¢ promotion. The multi-centre roadshow brief called for a compact, portable display solution that could be erected and dismantled in the minimum timeframe, which was met using 3m wide x 2m high, double-sided TRIGA Backdrop Walls and Promotional Service Counters retro-fitted with headphone cradles and laptop security brackets.
