POSA (the Korea Postal Service Agency / 한국우편사업진흥원) has released a series of lighthouse related graphics on the K-stamp Facebook page. The graphics show tourism related cancellations with Korean lighthouses shown in the cancellation. According to POSA “it’s a journey along the country’s lighthouses by tourist datestamp”.
The lighthouses shown on the “tourism cancellations” are from all parts of Korean including Incheon, Busan, Yeosu and Jeju (U-do):
The cancellations are a possible collection in their own right!
