I have a very large picture drawn by Alex Brychta who illustrates the Oxford Reading Tree - he came to our childrens book club and gave a brilliant talk. He asked the children what they wanted to see in the next story, the children just shouted out things and he drew them , like 'electric eel', it is an eel with a three pin plug attached and so on! It features all the children and is fascinating to look at. We auctionned them off as as he was my son's hero and turned him onto reading so I bought one, my son (15) still has it hanging in his bedroom as it reminds him of very happy days at his (state) primary.
Alex Brychta also came to our school during book week and did the same, lots of talks and illustrations on A1 size paper, which we framed and hung in the school.
The point being, A B is very datark haired with shaggy hair and a beard and glasses! he says he is always in his books soemwhere.
