Just thought I’d make a thread on this (not sure if one previously exists), I’m kind of wondering the actual amount of these cards released. Its hard to find an exact answer but I was snooping on the archives of pokegym and found links to some pictures for your viewing pleasure at least
Interesting do you know what the event was and where it was? I think I read somewhere that it was in New York, not too sure though.
So do you suspect the other half is lost in collections in the area where the event was held?
As for what’s inside the pack you’ve linked: just usual Expedition Base Set cards (without Sample stamp) according to @poketrade , which he mentions in this thread of someone asking the same question: E-reader sample pack, whats inside?
