I remember when I first saw images the guy from Where's Waldo (or "OI! WHERE'S THAT WALLY LAD, INNIT?" in the UK) in 2017, not long after I returned from a trip to Toronto. His face was showing up throughout all my regular neighbourhoods. I eventually learned (probably embarrassingly late, given how long it takes me to actually look stuff up on social media on my own) that there is an Instagram account for this artist that features a far greater range of variations on this face. It's become so common for me to see him around that I don't take many new pictures, but it always cheers me up to see he's still around. Much easier than the fucking nightmare that is the actual books.
Edit: the artist is taking a hiatus, but I'm sure I'll still see lots of these around.
