Idol group Infinite's first solo concert posters have been sold out.

On February 11 to 12, Infinite will be hosting their first ever concert 'Second Invasion' in Seoul Olympic Stadium. All 8,000 seats were sold out within 5 minutes of its open ticket sale.

In response to the enthusiam, Infinite made individual concert posters as a fan service. But as Dong Woo and Woo Hyun's first round of posters were posted on the streets, fans took them home instead for personal keeping.

CJ E&M Concert promotion stated "Two other members posters will be released by the end of this week" and "we believe it'll dissappear just as quickly. The feedback for the posters is very good".

Infinite associate also commented "because the tickets sold out so fast, we made the posters more as a fan service then promoting devices. We're very happy and thankful for the hot response".
