About the numbers behind the character, I flipped the image, tried my best to identify the number and it’s pair

713 …. 47X
765 …. 464
706 …. 447
824 …. 499
975 …. 595
937 …. YX0
726 …. XX1
729 …. X47
652 …. 400
653 …. 407
565 …. X75
746 …. XX8
1021…. XX9
759 …. XX5
718 …. X38
737 …. 469
648 …. 428
818 …. 520
985 …. 621
2154…. 1307
841 …. 540
71X …. 471
75X …. 489
689 …. 447
1017…. 658
1280…. 625
684 …. 448
.       …. 453
.       …. 860
.       …. 514
.       …. 496
..      …. 4 (maybe)

That leaves a 32 characters/phrases possible

The most interesting is the last number that I put as ending in 4, that one is clearly visible that it exists in the border of the print, its just a black dot of printing, and in my opinion cements the 32 words/characters in the list.

I didn’t try to discover some numbers because that would be really prejudicial to try and discover something.

I tried some 32 base encoding, and some other methods to try to explain X . Y , nothing still… tried converting to binary and adding/subtracting with nor/xor to a 469 cypher but nothing…
