The project to take special pictures of the crews of all the lifeboat stations around the coast received a boost with more of the prints being acquired by the National Library of Wales, based in Aberystwyth.
In January 2017, the Library acquired 20 of the limited prints of photographer Jack Lowe.
The prints of Aberystwyth, Angle, New Quay, St David’s and Tenby are preserved in the National Collection of Welsh Photographs, which includes more than 950,000 photographs connected to Wales.
In addition, the Library launched a year-long special exhibition of those 20 prints to celebrate the Year of the Sea in 2018.
Recently, the Library has chosen six more photographs, three from the town of Conwy and two from Moelfre and one from Trearddur Bay on Anglesey.
Mr Lowe began the Lifeboat Station Project in January 2015, and aims to have visited all 238 lifeboat stations in the UK and Ireland by the end of 2022.
The RNLI explained: “The photographs are created using a method called Wet Plate Collodion, which is a Victorian process that captures striking images on glass.
