Fix image in publisher file

I have the following light-bulb image in Microsoft Publisher and am unclear about how to have the phone number appear over it.Sign2.pub.txt

I have tried putting the image alone on the page and setting the picture formatting to 'through' and to 'none' and neither option seems to work.  I have tried the same formatting while making the picture the background for another text box as shown in the attached publisher file.

Assistance is greatly appreciated.
