A collection of 1,606 stamps featuring the Chinese chrysanthemum has been officially recognized by the Guinness Book of World Records for containing the most stamps in a single series.

A representative of Guinness World Records made the announcement on Tuesday at the annual Kaifeng Chrysanthemum Festival in Central China's Henan province, where cultivation of chrysanthemums has a more than 1,000-year history.

First released by China Post Group in 2012, the collection features 1,606 types of chrysanthemum flowers grown in the city. The flowers were depicted in a traditional Chinese painting style.

It took the group four more years to release all eight sets in the collection. Copies of the collection will be sold for 1,606 yuan ($238).

It was not the first time a world record has been set at the festival.

In 2015, a "full-standing multiflorous chrysanthemum" grafted in Kaifeng earned its place in the Guinness Book of World Records for containing the greatest number of chrysanthemum species.
