Set #300134 Austrian Riding School Play Set included the Leaping Lipizzan, Playful Arabian, Prancing Foal, Rearing Andalusian, Jump, 4 Flower Pots, 2 Standing Banners, 1 Trainer Doll, 1 Rider, Shed, Play Mat and Riding School Backdrop in a vinyl backpack. This set was initially thought to have been released later in 2008, as it was not pictured in the 2008 catalog; however, the date on the package is 2007. This was on both the 2008 and 2009 Retired Lists.
Side note: In my opinion, this set can be difficult to find, so I'm hesitant to say this set was available for 3 years. The date on the package may have been printed before the set was actually released.
This model is similar to the Set #300110 Chincoteague Island Beach Party Play Set, but this one is a more heavily shaded flea-bit chestnut, with a lot more flea-bit spots.
