Design the number nineteen ('19') with a bold outline, including the '1' and '9'. Inside the '9', which has a circular top and a downward tail, place up to 5 small, proportional toy images such as toy trucks, plush animals, or small balls within the circular top. Important: Ensure that the number '19' and all toy images inside the '9' have no internal color whatsoever—only black outlines. There should be no shading, filling, or any color other than the outlines. The tail can be left empty or with minimal detail. Ensure all elements are contained within the circular part of the '9', with no lines or divisions inside.
