The appearance on the 1987 insert in Germany
could provide an explanation for how carded ponies were sold
in this area - but the fact that accessories are illustrated
on the flier suggests that these were the full sets and not
the carded versions. If correct, it seems that the Play and
Care Set babies might have been sold in Germany in 1986, and
then this set (originally sold in North America in 1985) were
subsequently released there.
Baby Moondancer (Painted symbols, no Pat. Pend)
Europe, circa 1987
Although glitter can come off/be removed
from the original babies' symbols, the painted symbol
ponies tend to have no Pat Pend on their hooves, which
makes them easier to identify. This is also an indication
that they may have been sold later in the line. The fact
that the same artwork from the insert is also on the card
(English version pictured below), makes me inclined to
believe the carded versions were sold in Germany (probably
with painted symbols) in 1987, and the images have just
been taken from the US packaging, rather than being
indicative of pony accessories in this release.
