While we're figuring out radios, here's a pic from a 1928 Amazon expedition... any ideas?

Not quite as old, but still remembered.

Looks like Porter made lamps that were speakers. The radios were probably just to prove the point

Looks like some sort of lamp, apparently another  "hidden" loudspeaker design?   Must be the "Alladin Lamp", although the bulb shape looks more like a radio tube than a lamp.  But back then they did have light bulbs shaped like that.  The attached cord seems to have a standard Edison light bulb screw base for a connector, must have been  to screw into a lamp bulb socket.  Maybe the loudspeaker audio was used to modulate the intensity of the lamp?  Anyone know how far back the Edison lamp screw base, which is AFAIK, the same one still in use today, goes?  I recently came across some very old light bulbs with various bulb shapes and filament shapes.  Many look more like tube filaments than lamp filaments, they glow very yellow/red and not very bright.  Interestingly, I saw that someone is marketing newly made "retro" bulbs like these, saw a display of them at a kitchen and bath design center, guess people would use them for mirror lighting or other accent lighting.

Notice that the Aladdin Lamp (radio) has a long extension cord with a light bulb screw-in base for power as mentioned in the texts.

Maybe it's a charger for batteries or a battery eliminator disguised as a lamp. The bulb might be a Tungar, or some kind that provides a little bit of light. In those days some people considered radio equipment unsightly. Just as today some people formally keep the TV and stereo out of the living room or parlor, and have a separate room for media and 'fun'.
