I thought there would be some hard cover books from which I could remove the covers to re-use them for painting, but actually there were only one (physics) and two tiny Watchtower books.
I cut off the covers from all of them. Sure it is a sin to destroy a Watchtower book, isn't it?
Anyway I did some doodling on the first cover.
There was an embossed title on it. Something like "Is the Bible telling the truth" or so. It showed up through the paints so I glued some paper over it. Looks a little strange.
Not a big problem because the whole painting looks strange.
However it was fun.
