This morale patch is an homage to the WW2 divisional badge of the British Army's 49th (West Riding) Infantry Division, and in particular to the (sadly no longer existing) Duke of Wellington's Regiment, which was Bloke’s choice for representing when wearing old military uniforms in videos. Or alternatively it's an homage to a particular type of Glacier Mints. Or both. Your choice!
Patch size about 5 x 7 cm / 2" x 2.8", hook and loop base. Made in China.
