LOCATION Found standing by Arthes and Lopez in front of the stairway on the east side of Structure A-3.
CONDITION Unbroken except for some losses on the right-hand side, towards the base. The stone shows a tendency to spalling, and the lower portions are badly damaged, perhaps by fire (though Maler's attribution of this to careless use of fire for drying the molds must be rejected since the plaster cast reproduces the same deteriorated surface).
MATERIAL Fine-grained limestone.
SHAPE Parallel sides with low, rounded top. Front perfectly flat; back and sides well dressed.
DRAWING Graham, based on a field drawing corrected by artificial light and checked against the 1893 plaster cast.
