This is the very early and seminal days of "wireless" communications and likley this photo is over 100 years old.

Thank you Marconi and those that followed for your creativity and perserverance to believe all things are possible!

In this era of Covid19 our smartphones keep us connected and are a life line. Recently I was able to fill a much needed medical prescription right fom my phone. Thank You Marconi!
