Bold Pop Art Banner Design for 50+ Best Mockup Templates with Modern Graphic Style

Design a minimalistic and graphic pop art banner featuring a sharp diagonal split background dividing the canvas into two contrasting halves: vibrant bright yellow on the left and transparent grey checkered pattern on the right, symbolizing digital design environments. Place the main text '50+ BEST MOCKUP TEMPLATES' centrally with '50+' in an oversized, bold black sans-serif font and 'BEST MOCKUP TEMPLATES' underneath in a slightly smaller but still impactful weight, both rendered with clean, flat vector shapes and no texture to emphasize modernity and clarity. Below the headline, arrange six rectangular boxes in two vertical columns of three each, alternating between black stroke outlines on a transparent background and solid yellow fills with black text in a simplified geometric sans-serif font. The box labels read 'TSHIRT MOCKUPS', 'PACKAGING MOCKUPS', 'BROCHURE MOCKUPS', 'FLYER MOCKUPS', 'STATIONERY MOCKUPS', and 'BOX MOCKUPS'. Employ a limited color palette of black, bright yellow, and varying greys, and use strong, simplified silhouettes and negative space for maximum readability and iconic presence. The composition is balanced with generous spacing, emphasizing clean lines and graphic simplicity. Incorporate subtle drop shadows on text and boxes for depth without clutter. The viewpoint is a straightforward front-facing flat design, optimized for logo or sticker-like recognition and versatile multi-platform use from digital banners to print media. Include sleek infographic-style text along the bottom in a modern font about creating and posting designs quickly with Design Less Platform, promoting ease and speed in three simple steps, integrated seamlessly into the minimalist aesthetic with high contrast and no textures.
