Illustrate a vintage steampunk phone, a masterpiece of retro-futuristic design blending Victorian aesthetics with industrial innovation. The phone features intricate brass gears and cogs, meticulously crafted into an ornate, filigree pattern that adorns the handset and base. The dial, a series of finely engraved numbers and symbols, sits atop a polished wooden surface, exuding a warm, inviting glow. Copper wires coil elegantly around the body of the phone, connecting to a series of antique vacuum tubes that emit a soft, warm light. The receiver, embellished with delicate etchings and a velvet cushion, rests gracefully against the user's ear. The overall color scheme is a rich combination of brass, copper, and mahogany, evoking a sense of elegance and nostalgia.
