Apr 26, 2018· Hi forum, We would like to send an invitation to our customers to come and have a look/drink/chat at our booth during a big exhibition. It should be rather informal, but not too much. Here is a draft. It would be great if some one can comment it. Thank you in advance! Dear …, The world's largest exhibition for ...., 'NAME OF EXHIB' 2007, is almost upon us (5-9 June).
