Traditional Window Sticker Design for Grocery

I'm seeking a designer to create a window sticker for my grocery store, sized 400 * 40 cm. This sticker will primarily promote a specific packaged product.

The ideal designer for this project should have a strong portfolio in traditional and classic design styles, particularly in the context of retail promotions. Your design will set the stage for additional stickers needed in the future, so a versatile and scalable approach is key.

Key Requirements:
- Experience in product promotion design
- Proficient in traditional and classic design styles
- Able to create designs suitable for retail environments
- Able to create designs scalable for future needs
