Okay, let’s tackle this. So Noppadol has 46 years of experience in graphic design, which is extremely rare. Typically, experienced graphic designers can charge around $50–$100 per hour. However, considering his extensive experience and the fact that he has been working in the same company for 46 years, I would estimate his hourly rate to be on the lower side. Maybe around $75 per hour. This is because he is not a freelancer or a consultant, but rather an employee of a company. Also, his experience is not in a highly specialized field, but rather in multiple design fields, which might affect his earning potential.
