Vintage Tech Logo with Icon

I need a vintage-inspired logo for a technology brand. The overall feel should nod to classic engineering badges and retro circuitry while still reading crisply on modern screens. A distinctive icon or symbol must be the focal point—no standalone wordmarks this time—so the mark can work in app tiles, favicons, and social avatars without added text.

Think muted, heritage tones, subtle distressing, and balanced line work rather than busy ornamental flourishes. The logo has to scale smoothly from 24 px up to conference-booth banners, so clean vector execution is essential.

Deliverables
• 3 initial vintage-style concepts, each featuring a unique icon or symbol
• 1 chosen concept refined through up to 2 revision rounds
• Final files in AI, SVG, PDF, PNG (transparent) and JPG, supplied in full-color and single-color versions
• Usage guidelines: color palette, clear-space rules, and minimum-size specs

Acceptance criteria
• Icon is recognisable without accompanying text
• Vintage aesthetic feels authentic yet not dated or overly ornate
• Paths are tidy, no stray points; exports remain sharp at all sizes

Please keep all work original and ready for trademark registration.
