As if the packaging size and cardback layout differences weren't exciting enough, the in-pack premiums and corresponding offer stickers provide collectors with a whole host of variations to track down. Premiums packaged within the bubble and located behind the action figure include: mini-comic only, poster only, mini-comic and poster together, and lastly no premium whatsoever. Adhesive stickers are sometimes found adhered to the blister card's front to advertise the free poster inclusion, but some carded examples containing the posters do not contain the advertising sticker. Documented tri-lingual Joker packaging variations include:
The tri-lingual carded Joker photographically showcased at the beginning of this entry comes packaged with its mini-comic. The inclusion of a small white adhesive sticker containing German text on the upper right hand packaging corner leads me to believe examples containing these stickers were intended for distribution in the German market.
The mini-comics packaged within trilingual packaging contain unique qualities compared to those found in Kenner and Kenner Canada packaging. The tri-lingual mini-comics utilize much higher quality and much glossier paperstock. The action figures contained within European tri-lingual packaging do not exhibit visual differences compared to figures sold in the US and Canada. To date it appears only the first twelve 1st series characters were sold on this unique packaging style.
