Lost copy of 'The Great Gatsby' with a simple black cover and a personal sketch near the park in Altoona-Johnstown.

I lost my copy of 'The Great Gatsby' while walking my dog near the park in Altoona-Johnstown. It has a simple black cover and contains a sketch I did in the margins which my grandmother drew for me as a gift. I really want it back as it has sentimental value.
