Hello to all of you I want to tell you that I have written permission from the artists to use their art for tubes. When the artist says NO to me I do respect that and don't use the art.Most of the artists also wanted that I make a link to their site and give them credit for the pictures wich I did ! And I also can say that that each tube is made by ME ! I don't rip off artists ,if they asked me to remove the tubes because they don't agree any longer for some reason I will remove the tubes immediatley. I'm sorry that you didn't asked me first about the use of art, you all could have used the emailbutton on my site! Mackie I
