Interesting signs! This article explains a little more:
The 32 Signs of a Great Man (mahā purisa lakkhaṇa)
are auspicious marks that are supposed to be present on the bodies of all Buddhas.
Although only incidental to Buddhism, this idea is the theme of three discourses (D.II,142; M.II,133; Sn.103) and is mentioned briefly in several others. The idea of the Signs has its origins in Brahmanism and was incorporated into Buddhism at a later period for reasons that are not clear.
Some of the Signs, like the long tongue, the blue eyes, the golden complexion and the ensheathed penis, were probably connected with the ancient Indian concept of idealized physical beauty. Others are so strange, grotesque even, that it is difficult to know what to make of them.
When the seer Asita came to visit the new born Buddha-to-be, Siddhattha Gotama, he mentions that he sees the signs or marks of a great man and lists some of them. This confirms that this concept is a pre-Buddhist idea.
It is very clear from the Tipitaka that the Buddha's physical appearance was normal in every way. When King Ajātasattu went to meet him he was unable to distinguish him from the disciples surrounding him (D.I,50). If the Buddha had any of the 32 Signs the king would have recognized him immediately.
Pukkasāti sat talking to the Buddha for hours before realizing who he was (M.III,238). If the Buddha had any of the Signs the young man would have soon noticed it and known that he was someone unusual.
When Upaka encountered the Buddha walking along the road to Gaya the thing he noticed most about him was 'clear faculities and radiant complexion' (M.I,170). He did not mention seeing any of the 32 Signs.
In the Buddha's teachings, the external and the physical are always subordinate to the internal and the psychological (S.I,169). The Buddha was aware of the Brahmanical concept that a ‘great man' could be known by his physical characteristics and he rejected this notion. Someone once asked him: ‘They talk about a ‘great man,' a ‘great man.' But what is it that makes a great man?' The Buddha replied: ‘It is by freeing the mind that someone becomes a great man. Without freeing the mind one cannot be a great man' (S.V,157).

Note 2: "His lashes are like a cow's; his eyes are blue./ Those who know such things declare/ 'A child which such fine eyes/ will be one who's looked upon with joy./ If a layman, thus he'll be/ Pleasing to the sight of all./ If ascetic he becomes,/ Then loved as healer of folk's woes.'"
