I was going to post a picture of a bank note I tried to use a couple of weeks ago. It seems it is no longer in circulation, so the shop refused it. That I have an out of circulation bank note shows I have been out of circulation also.
Then I thought it might be illegal to post a picture of a bank note. As far as I could tell it is OK as long as part of the note is obscured. So I used these stones to hide part of the note. Not sure if that was even necessary as it is no longer in circulation.
Then I decided the stones looked better without the bank note.
Why do I have a bag of stones. Well I did wonder that myself. A while ago I had an indoor fountain, and I think these stones may have been for the fountain.
The picture is not quite mono, but could look as though it is.
