1980s Panasonic Portable Phone, model EB-1118. This vintage unit comes with original shoulder strap, battery and power cord. The antenna is after market. Though not in perfect condition (the rubber handle on top is broken in the middle, the power cord has some electrical tape where the cig lighter charger plug is attached & the body has some very minor shelf wear/blemishes), but the unit powers on, produces the sounds, and the keys all operate (see photos). 

Fun Fact: Contrary to pop culture imagery of  Colombian drug kingpin Pablo Escobar, it wasn't a Dynatec brick phone he most often used, but rather a model similar to this one; (here's a link to an article with his National phone - https://thevelvetrocket.com/2009/09/30/the-museo-historico-policia-and-pablo-escobar)

*Please note: I have uploaded a brief video of the phone plugged in, to show it works, but - Ebay in their infinite (non)wisdom may not show you on the app because apparently Ebay is inconsistent/annoying/stupid. So, that said (and hoping Ebay sees this commentary & understands how much I despise them) if you cannot see the video, just message us and we'll send it to you.
