And my dad probably bought from yours.
My dad was Chief Engineer at City Ice & Fuel then Royal Palm Ice Co, in Miami & Miami Beach, 1929-1962.
Provided ice for the hotels on the ‘Beach’ (WW2) that housed military and others. Also provided for small PT boats and other Navy ships that did not have ice makers.
If you had ice in Miami/ Dade then, he probably, was making it.
