Growth is an exhibition at the London Science Museum aimed at 12-16 year olds. The exhibition is based around DNA and how this subject could effect our future. The brief asked for an identity and invitation to be designed that related directly to the concept of DNA. With DNA the strands that connect them are equally, if not more important, than the parts themselves, so in the brand the strands create the identity. The envelope is a foil retort bag that keeps the invite air-tight inside it.
