A vintage-style technical illustration showing a small flip phone and an early smartphone floating in space, connected by two distinct glowing data streams - one simple and direct like a straight arrow, the other elaborate and wrapped in decorative envelope layers. The devices hover above a stylized globe with tiny radio towers. Warm sepia and amber tones dominate, with cream-colored parchment texture in the background. The aesthetic evokes 1950s technical manuals and retro-futuristic diagrams, with crosshatching details and aged paper edges. Small XML-like angular brackets float decoratively around the data streams without forming actual words.
