Here's a somewhat busy Sonic Boom cap. It's a white & gray hat with screen-tone dots, stripes, paint spatters & Sonic Tails & Knuckles in CG on the front. The Boom logo is at an angle on the bill. The trio are full color CG....but the Sonic is outlined by a thick, black line. What is this? Is he an added element like a puffy-patch that's embroidered on? Tails & Knuckles are "shadowed" against the cap's pattern to make them look 'popping out' of the design...but what exactly is going on with Sonic? This cap is a late 2016 item, but where is it found?
