Bold signature on a 3x5-inch white card of the prominent astronomer who discovered Pluto in 1930. Pluto lost its status as a planet in our solar system following a meeting of the International Astronomical Union in 2006. In good condition, with the tiniest hint of crinkling at the top; the writing grazing the card's right edge; and two negligible flecks of soiling. Not bad at all, but mentioned for the sake of total accuracy.
