How?
Step 1. Build a list of the rows of the right half of an empty briefcase, ignoring trailing spaces:
⁽©Ḍṃ“_= ”x"“€Þ‘x2,6¤;"⁾_|x1,7¤
“_= ” - literal list of characters = "_= "
⁽©Ḍ - base 250 literal = 2674
ṃ - base decompress (2674 in base: 1='_', 2='=', 0=' ')
- ...yields the list of characters: "_ = _"
¤ - nilad followed by link(s) as a nilad:
“€Þ‘ - literal list of code page indexes = [12,20]
2,6 - literal list of numbers = [2,6]
x - repeat -> [12,12,20,20,20,20,20,20]
x - repeat -> ["_"*12, " "*12, "="*20, " "*20, ..., "_"*20]
¤ - nilad followed by link(s) as a nilad:
⁾_| - literal list of characters = "_|"
1,7 - literal list of numbers = [1,7]
x - repeat -> list of characters "_|||||||"
" - zip with the dyad:
; - concatenate -> ["_"+"_"*12, "|"+" "*12, ...]
Step 2: transform that into a whole empty briefcase:
z⁶ZUŒBY
⁶ - literal space character
z - transpose with filler (adds the "leading" spaces, to the 1st 2 rows)
Z - transpose (back from columns to rows again)
U - upend (reverse each row to make it a left-hand side of an empty briefcase)
ŒB - bounce (add a reflection of each row with one central character)
Y - join with new lines

134 - literal 134
+ - addition -> [135,138,139,140,141,142,145,146,147,148,149,152,160,173,177,180,184,187,191,194,195,196,200,201,202,219,222,226,229,233,236,239,240,241,244,261,264,265,266,267,268,271,272,273,274,275,278,286]

The ultimate question: what is the width of the briefcase? – Rodrigo A. Pérez – 2017-06-17T01:55:52.137
@cat Oops my bad – Weedoze – 2017-06-17T14:37:34.910
@RodrigoA.Pérez Already told in the question. 42 characters – Weedoze – 2017-06-17T14:37:50.960
@Weedoze Yes I know; the ultimate question... – Rodrigo A. Pérez – 2017-06-18T02:31:55.877
... It's 41 characters wide – ASCII-only – 2017-06-18T05:25:42.297
