Trade
cards in this category consist of a single piece that is
normally folded closed and has multiple folds that unfold
(fold out) to form a much larger card that is usually
square.
This category should not be
confused with metamorphic trade cards which also employ
folding parts, or foldover trade cards which are folded to
form pages like a booklet.
There are not many cards to
be found in this category.
Some
examples are shown here at 25 percent of actual size. Click
on a card for a larger view and a description that includes
the price it brought at auction (without buyer's
premium).
