-Galaxy holofoil: Also sometimes known as starfoil due to the appearance of stars. This foil pattern was the one used
for the english print run of base,jungle,Fossil and Legendary Collection
-Cosmos holofoil: No stars, more of a dotted,bubbled pattern. This foil pattern was the one that replaced the galaxy foil starting with base set 2 (Base 2 was the set after fossil), then Team Rocket, Neo Series,etc. Note that some foreign print runs used this cosmos foil as well.
Cosmos Fossil Complete Set:
It is interesting to note that the zapdos cosmos holofoil has the 1999 copyright rather than the typical 1999-2000 copyright which came from the Tempest/Thunderstorm themedecks.
