This comic page is from one of my all-time favourite Christmas comic-tales, from WHIZZER and Chips , issue dated 26/12/1970.
Fantastic twist at the end of this story, one that really captured my imagination: Bravo! to 'Tezza' and the scriptwriter responsible, of course!

Going by the dramatic ending to this outing, this looks like the very final instalment to this concept's run what with Smudger Smiths' creepy Nemesis losing his free will and individual status---however the strip did return, with Shadow returning to his mischevious, independent ways.
I'll be adding more vintage comics strips of Christmas themolgy on this thread, on the run up to the 25th.
