They issued a 5 bobblehead set during the 2009/2010 season, which included Lanny, Vernon, Iggy, Peplinski (?), and Harvey the Hound. They were the full-sized bobbleheads and the boxes (and the base) each had the 30th Anniversary logo. I'm not sure how they distributed those but I do believe season ticket holders received a set at the end of the year.
I suspect these will be the slightly smaller versions that have popped up in recent years (like the Johnny Gaudreau ones they sold in 2017/18 for Kidsport, and the Jon Cornish bobbleheads the Stamps issued for his CFL HOF induction this year -- they gave away 2,000 and also sold them at the game).
