You mean this one Brent...
Coincidentally, I just got mine on Monday! Finally! It's even nicer than the one pictured above (perfect sticker).
A very helpful and good friend on the boards hooked me up with a minty-mint one for a good price. Very pleased I am with my latest acquisition - only the third "foreign" item in my collection (along with the Bonus Pit Droids and Mexican POTJ 4-pack).
For those that don't know the history of this particular piece, it's the regular Dagobah Vader from the POTJ line, but on a Tri-Logo card, BUT with a good sized triangular sticker at the base of the bubble saying and showing "Secret Luke" - with a pic of the Vader mask with the piece missing to expose a portion of Lukes face underneath. (updated with a picture now!) Very cool, and NEVER available here in the U.S. I've only ever heard of it being found in Canada. Does anyone know if it was available anywhere else?
As for the price on it, it's dropped down to around the $45 - $60 range for the most part (on eBay). Used to go quite a bit higher than that for quite a while. It's one of the VERY FEW "foreign" pieces I ever felt was a "must have" to keep the collection complete - due to it's uniqueness (basically just the damned sticker).
Thanks a bunch D!
