Scratch-n-sniff

From its lenticular covers to its weekly events to its wanton hiring of Rob Liefeld, DC Comics has brought back a lot of comic gimmicks since starting up The New 52 in 2011. The newest one will involve Harley Quinn and your nose. That's right. Harley Quinn Annual #1 will be a scratch-'n'-sniff issue, with the smells of leather, suntan lotion, and pizza included. There's also a smell that's purported to be cannabis. That one will be replaced in international issues with "fresh-cut grass."
