as3 A stunning modern collectors postcard of Cone Nebula which s a faint constellation on the celestial equator. Its name is Greek for unicorn. Its definition is attributed to the 17th-century Dutch cartographer Petrus Plancius (this is not mentioned on reverse but on google). It is bordered by Orion & Gemini and reverse however does detail the Cone Nebula with great information and the image etc making this a most specialist souvenir for any astronomy collector unused and mint
