Create a vintage blank telegram sheet from Hong Kong circa 1890. The paper should have an old, slightly yellowed appearance with subtle aging marks, like creases and faded edges. Include a formal heading at the top that reads 'Hong Kong Telegraph' in elegant, ornate lettering typical of the 19th century. Below, leave ample blank space for writing, with subtle, faint lines or grid marks to guide text. Incorporate decorative borders and the Hong Kong government seal in one corner, giving it an official, historical feel
