"Llyfr Mawr Hwyl!" By Ivor Owen (published in Wales, UK in the early 1950's)

This is a Welsh language comic book for children published and partly drawn by Ivor Owen. Great characters and fun stories through out - needless to say I couldn't read a word but the pictures are quite unique. There is a feature on a similar volume, published by the same author, on Steve Holland's brilliant blog: https://bearalley.blogspot.co.uk/2012/06/hwyl-llyfr-mawr.html This blog has a vast collection of old British Comics and other books.
