Pathwalker - yes, if you open a pdf up in an Adobe Reader and it's locked you won't be able to edit it. But if you open it up in image editing software like Photoshop you can.
Can't you copy a fraction of the picture (that part that contain the text), paste it and move it a little to the left? (that would cover the original text and you could center as you wish) (I haven't used Foxit Reader, I'm not sure what this program can or can't do).
Thank you all for this - some of the tech stuff is going over my head, but I get the general idea - and thank you for the scans.
Hope this all might enable other folks to have a personal copy of this great artwork,
