A memory I didn't know I had was awakened as I turned over to the Obituary pages in the Guardian last Saturday. The obituary was for Angus McBride, artist and illustrator, who drew illustrations for "Look and Learn". You can see some of his illustrations for that magazine here.
There was an example of McBride's illustrations in Saturday's Guardian. It included the magazine's masthead (above). It took me a while to remember where I had seen said masthead. In the end I realised it. I used to get the magazine on a regular basis - delivered alongside my brother's "Eagle" comic.
There is an excellent web site devoted to Look and Learn here.
