I've got it finished, but it's "invalid" I've double and treble checked it and the picture even looks correct. Must be more than one possible solution!
Ok, so this is long overdue, but if anyone should want to try this puzzle at this point, here are some hints: Row 6: the 1's are in columns 1, 5, 8, 18, 21, 25 Row 7: squares 1-2, 4-5, 9, 12-14, 17, 21-22, 24-25 Row 19: squares 1-3, 5, 9-17, 21, 23-25 Row 20:1-4, 8, 12-14, 18, 22-25 It's somewhat symmetrical - you'll see that the single squares form a sort of "X" down the middle - they outline a white "x," that is.
Yes, what LeraDraco said is correct - it's supposed to be a Blackhawks logo - two crossed tomahawks over a "C."
Again, I apologize for this one not being logical. :/.
