First Class Mail Carrier Mug

Design a vibrant, professional graphic illustration featuring the quote "First Class Mail Carrier" alongside a prominent, vibrant blue rural mailbox with its red flag raised. Showcase carefully sorted letters and packages, with envelopes sealed by distinctive red heart stickers. Seamlessly integrate the empowering slogans 'Delivering joy One Stop At A Time' and 'Sorted, Sealed & Delivered' into the composition, perhaps as elegant text overlays or subtle design elements on a uniform or vehicle. Ensure a high-quality, detailed illustration with bright, appealing colors, crisp lines, optimistic composition, and professional lighting for a polished finish.
