The Herter's catalog was the highpoint of my youth in the 50s. Everything was marketed as "Professional", I still have my "Professional" tanning and fly tying guides.
I had a paper route and would save my pennies to buy fishing stuff. It didn't matter how small an order was, they would fil it, I remember sending one in for 35 cents worth of hooks.
I tied all my lead heads with the illegal polar bear hair from them (no one knew it was protected). Fines and legal issues eventually sunk the company.
I still had a stash of Herter's fishing dry flies, spoons and lures in my tackle box until about 30 years ago when I left my tackle box in my boat when I returned from a afternoon fishing trip. I parked my boat in the driveway of my house in our subdivision planning to go fishing at first light the next morning. When I got up to go fishing I found that some lowlife had relieved me of my tackle box over night.
