# ancient paper
## Description
- We are given an image file along the following description: “I found this ancient artifact stuck in an old machine labeled “29”. But what is its purpose?”
## Solution
- Initial inspection leads to the conclusion that the image is of an IBM-29 punch card which was carrying our flag as its data.
## Decoding the flag
- Then I used the following mapping of the IBM-29 punch card to decode the data.
![digit_table](https://w1r3w01f.github.io/images/digit_mapping.png)
![alpha_table](https://w1r3w01f.github.io/images/alpha_mapping.png)
- Which lead to the following text:
```
1337 FORMAT ENO H0LL3R1TH 3NC0D3D F0RTR4N PRINT 1337
```
- And hence we get our flag as:
## Flag
`ENO{H0LL3R1TH_3NC0D3D_F0RTR4N}`
