UK-based design agency Purple Creative has celebrated its 20th year of business by designing four whisky bottles to house its limited edition blended Scotch whisky.

A total of 200 bottles of the 'XX Whisky', which has been especially to celebrate Purple's milestone, will be given to the people and companies that have helped Purple Creative since it began back in the 90s.  

Each of the four bottle designs, which were illustrated by Chris Martin, feature stories and memories that Purple has gathered during its 20 years in the creative industry, from the white van that Purple's three founders travelled around Europe in during their final year at university to a practical joke gone wrong that resulted in a bin explosion.

The four bottles have been finished in midnight black, with screen-printed white illustrations. A Corian stone stopper can be found on top of each bottle.
