IC 3257 is one of Bigourdan's "fausse images." He has one observation of it in April of 1895, calling it a "Trace of nebulosity nearly completely unseeable." In May of 1907, he said, "I can once in a while see this eF object," but made no measurement of it. There is nothing in his position.

Malcolm pointed out that the declination of Bigourdan's comparison star is incorrect in the big table of observations. Nevertheless, the position in the IC is reduced correctly, so this is just a typo.

Malcolm also points out that the object at Bigourdan's position seen on the red POSS1 -- thus also on DSS -- is a defect. It is not on the blue POSS1, nor is it on the POSS2.
