Since I also inquired about the postcards on page 99 of this thread, here is the information I have.
There are six sets: Postcard Set A (1998), Postcard Set B (1998), Postcard Set A (1999), Postcard Set B (1999), Postcard Set A (2000), Postcard Set B (2000). Also there are the Southern Islands postcards which are a bit more well known.
They were all illustrated by Keiko Fukuyama. Theyāre indeed stunningly beautiful, but also pretty pricey (~200 USD per postcard last time I asked). As a substitute, you can find high resolution scans of most (if not all) of them here: seiry-pkmn.tumblr.com/tagged/postcards
These just arrived. Raw, complete sets of EX dragon, sandstorm and ruby/sapphire. Plus a few random EX cards and other reverse holos that I needed to upgrade. The condition is just stunning. Every card mint or gem mint. For those that collect EX era cards, it is VERY hard to find pristine reverse holos for these three sets (and TMTA) as they are delicate and scratch easily. Thank you to the forum member who opened these so many years ago, took such amazing care of them and now sent them to me. I pledge to do the same! Itās like a time capsule straight from 2003. What a treasure.
Another one down! In reading that there are correct and incorrect artist versions, decided I only care for the correct artist card which is definitely harder to track down! I always thought Zapdos was my favorite of the trio, but this card starts to make me think otherwise! Emailed PSA and hoping they will differentiate the versions in their system. Iād be pissed if my name didnāt get on the card I drew!
O.M.F.G. Iām in AWEEEEEEEEEEEE Over this. Literally my jaw hit the floor. Iām SOOOOOOOOOOOOOOOOOOOOOOOOOOO jealous. This brings me beyond the measure of Jealously!!!
