With the grouped objects still selected, choose Edit > Copy.

Click the Next Page button () in the status bar to display the Right master page. Don’t click anywhere on the page, because if you click inside a text frame, the graphic will be pasted inside the frame instead of at the top of the page.

Choose Edit > Paste. The graphic appears at the top of the page, in the same position as on the Left master page.

The page header disappeared, because the graphic was pasted in front of the header text frame.

With the graphic still selected, choose Graphics > Send to Back. The header text frame reappears.

To make the notch in the graphic (created by the white rectangle you drew in the previous section) appear on the left, you’ll flip the graphic.

With the graphic still selected, choose Graphics > Flip Left/Right.

If you want, choose View > Body Pages to display the first page of the document, and then scroll through the document to see the modified headers and footers. When you’re finished, choose View > Master Pages and make sure the Right master page is displayed.

Save the document.
