A really nice green ED Bullard hard boiled hat. Manufactured in San Fransisco. The interior label has daded to the point that you can't read the model or any other information.
Logo for Daniel International Construction and the word "DANIEL". The front features the numbers "80" over "013" and 4 (what I perceive to be) safety owls.
Daniel IC was bought out in 1977 so that would be the latest this item would be from.
