One of the reasons that it may seem that, compared to Disneyland, there were far fewer cards for WDW during its first decade is that generally WDW views from those first years stayed in print much longer. Much of the cause for this is due to the fact that WDW was so much more fully developed at the time of it's opening than Disneyland was.There was not as much need for replacement views, as the landcaping improved, and attractions were added, as there was at Disneyland, which being the first amusement park of it's kind... make that the first true theme park, went through many changes and series of post cards in it's first dozen years. Four full series of Disneyland photo chromes were issued (with some repitition from the third to fourth series) in those years, five if you include pre-opening Disneyland cards. The Magic Kingdom on the other hand had only two full series (three if you count pre-opening), the 0111-0000 series was only a partial series it did not replace the 01110000 cards which stayed in circulation. It seems to me that Epcot was built even more fully formed than the Magic Kingdom. According to Since the World Began by Jeff Kurti Epcot was "the largest private construction project in the world" (page 89). Also it's cost is listed as between $800 million ans $1.2 billion. Knowing how much of the park was completed up front perhaps it should not be seen as surprising that many of the first post cards issued at Epcot were out for fifteen years before need for widespread replacement was seen, so much was already in it's finished form. Cards were added to the series over time, but predominatly all the way up until near the end of the 1990s these were the main views of Epcot. This first series of Epcot post cards left a lasting impression indeed!
