Something tells me that Harry's the only one brave in love enough to stand on Severus' left when Severus is sporting that particular novelty T-shirt. ;¬)
Their hair cuts are groovy, oh favourite mystery penciller. I see Severus belongs to the Joan Jett hair club. Sweet! Harry, on the other hand, looks like he favours The Beatles' style.
Harry's 'Windsor flappers' are ever so splendid, & their expressions are priceless! ❤
