A treasure map falls out of an old book what would you do?

I  bought a  constellation celestial globe  for myself at Christmas  £2.99  in the offers  bin   it is  made in China  and  although accurate  shows the  constellations as they are  seen at 27 degrees  north,

I also bought a  number of  second hand books  from charity shops  buying second hand I am used to finding  bookmark  postcards,, shopping lists entry passes to Anglo  DDR trade fairs  ,  Manchester metro  tickets and Parisian  billets  inside   and from a 1987 copy of the Mabinogion  marking  a page  from the   second  branch   Branwen ferch  Llyr   with  underlined text   " they scoured the  land   wherever there had been  battles; they  found  gold and  silver  and became  wealthy  "

I found this drawing of an  island  with writing  beside it

was this   ball point drawn  a  treasure  island  map

The island  drawn    does nor look like  a typical   Kidd- Palmer  Chart , the Oak island  money pit or  Cocos  island   and the  clues  seem like  scribble   than a warning to the  curious

the clues  resemble big sum maths  so are best left alone !

what  treasures are left to be found ?

  in  Pirate loot there is only left to be  located    the  sunken skeleton of  Captain " Black  Bart " Roberts intertwined with his   Emerald  Cross

 In lost  treasures  of history  only the Tomb of Alexander ,   Atillas   hoard   or the   Roman loot of Alaric the Goth  remain to be found

Alexander's tomb seen as a glittering crystal cave in the 1963  epic cleopatra  has  been discovered in so so   many archaeological  chase thrillers everywhere from underwater  Alexandria  to St Marks Basilica  in Venice   ( if in my  opinion  the  most historically  realistic  accurate  location  of  the Tomb of Alexander can be  found in Richard  Blake's   novel the  Blood of Alexandria)  and was not Attila's hoard discovered  intact  in Robert Lowe's    first and best  novel in the  Oath  sworn series.

re  Gothic  Roman loot from the temple   of  Jerusalem   a   recent theory  traced  this to Sub arctic  Russia  and  seventeenth  century  travellers  tales   of    Samoyed   golden idols . 

As for  the map   and its big sum cipher     it may be more likely drawn   from    Jonny  Quest   and the Tibetan Diamond  Caper   and   as  for  my taking time  in  cracking the code  it is useful to recall   the artist Kit  Williams  Masquerade  picture book from  the   late 1970s    a best seller on  the   clues within leading readers   to the buried  treasure of the   golden Hare which was   eventually  "discovered"  by  someone who had  never read the  book  and was   told of the  gold  cache  by a publishing insider 

all I can say  is  that    the    is there an X  marks the  spot on the  map ?
