Inspiration 

A tribute to my mentor. 
 
Reflecting upon my time with the King’s Trust, a wonderful chapter in my life when multiple opportunities paved my path towards incredible experiences. Each extending aluminium arm symbolises a distinct path taken; moments of growth, invaluable life lessons. Creative collaborations, inspirational talks as a young ambassador and of course, meeting His Majesty, King Charles III
Aesthetically, the GM-18 draws inspiration from my long-standing appreciation for the Art Deco movement. An era defined by confidence, elegance, and beautifully disciplined lines. Its influence felt especially fitting, not only as a personal aesthetic reference, but as a subtle nod to my mentor, whose own home embraces the timeless sophistication of Art Deco design. 
The name GM-18 carries a deeply personal significance. “GM” references the initials of my mentor, while “18” marks the year we were first introduced, a meeting that would go on to shape both my creative journey and personal outlook in profound ways.
