Since 2013 the French "Le Routard, Irelande" travel guide has written about the Icon Walk and are bringing a lot curiosity to French tourists.  The 2020 edition writes : 

"Temple Bar frescoes : An interesting walk on Adair Lane, Price’s Lane (the most interesting) and Bedford Lane. These 2 alleys were dedicated to artists and other graffiti artists (under the leadership of the artistic cooperative The Icon Factory) to put in images, often with beautiful texts, all the richness of Irish culture: from literature to rock music, history, cinema, sport... Take your time to savour the quality of certain representations, aphorisms, poems, humour (sometimes critical) illustrating many texts and situations... Too bad they are no longer maintained much! See iconfactorydublin.com for more details."
