The first is by Sempe, a well known French illustrator and cartoonist. I have one of his books and they have wonderful little snippets, done in his own style, showing aspects of French life. Great artist and cartoonist, with a real sense of humour and irony. The second picture looks like the work of Goscinny and/or Uderzo, the artists responsible for Asterix the Gaul. I could be mistaken, but there is something very familiar about the style here.
