I've got it! =)

The answer was on topic "Listing 6.7. Superimposing.java" of Chapter 6. Working with existing PDFs

PdfReader reader = new PdfReader(SOURCE);
Document document = new Document(PageSize.POSTCARD);
PdfWriter writer = PdfWriter.getInstance(document, new FileOutputStream(RESULT));

document.open();

PdfContentByte canvas = writer.getDirectContent();

PdfImportedPage page;

for (int i = 1; i <= reader.getNumberOfPages(); i++)
{
    page = writer.getImportedPage(reader, i);

    // You can invoke this command "n" times to create overlays, including with pages from other readers
    canvas.addTemplate(page, 1f, 0, 0, 1, 0, 0);
}

document.close();
