I’ve seen these glasses tags around. Someone turned it into a a Groucho Marx caricature, not sure how many kids of tagging age know Groucho.
This cute little character is pedobear , and he is one of those internet memes that may have escaped your notice. Basically it is a way to be really offensive without offending the unaware. It somehow has come to reference or allege pedophilia without overtly stating it. For example you might see a cartoon of pedobear in pope garb. Someone has been tagging with the image in Manhattan for the lulz.
