There's a tiny English-language obituary online at
The Independent and
ABC (Australia). Given the near identical wording I imagine these are wire pieces rather than anything in house. Maybe filed by an intrepid boy reporter somewhere?
There's a longer piece at
The Comics Reporter.
I've always liked the look of his work, and indeed have the two Ward Lock books from the 1970s, and agree they seem more animated than B&M, but I didn't really enjoy either book as I have done with B&M and, of course, Tintin. Maybe it is time to dig them out and give them another go.
Still, a good innings, as they say, and great to see a creator still active to the end, even if in a reduced capacity.
