Blue Ribbon

Win the grange display at the Stardew Valley Fair (Fall 16). Bring nine items, aim for variety and quality: items from at least six different categories (fruit, vegetables, fish, minerals, animal products, artisan goods, forage...), all gold or iridium quality. A display along those lines comfortably beats Pierre and pops the achievement when Lewis announces the result.

Not ready in year one? It returns every autumn - stash a box of your best iridium-quality bits through the year and it's a formality.
