You work at the local library and it can be ever so tedious.
So you decide to search through the archives for anything that might be of interest.
When searching through a box you find a sealed letter which isn't catalogued.
You're about to return it to your manager until you turn it over to see a red wax seal with what looks like an eagle printed into it. On the back it reads: "For the bold!".
You decide to open it an inside you find a coupon!
The letter reads:
Hello to you fortunate enough to find this letter,
Though I may be long gone my legacy may continue, therefore I will great you my life’s greatest treasure!
However you must first prove worthy of using such an item and for that I grant you this voucher.
It will show you to your destination and so you may find what you seek.
My identity will remain muddled for now but you may find me later in your adventure.
Measure your options carefully and good luck!

What should you do next?
Hint 1:
This is the original barcode (not resized or compressed):
The barcode number is: 114199211541116212432111
Hint 2:
Great this adventure would be,
Provided I knew where to begin,
So where is the clue I should see,
Can I ever get rid of my sin?
Hint 3:
Some claim it to be better,
Then any man-made before,
With only one of two options,
The language that paints the door.
I will post the next part when this is solved or if it remains unanswered for over a month!
