Lost paperback copy of 'The Great Gatsby' with a blue cover near a café table at the River Walk in San Antonio.

I misplaced my copy of 'The Great Gatsby' while visiting the River Walk in San Antonio last weekend. It's a paperback edition with a blue cover, and I remember putting it down at a table near one of the cafes. I'm really hoping to get it back as it holds sentimental value to me.
