GRGR(9): Yellow handkerchief

[Jeremy Osner]

On p. 184, Slothrop "produces a gaudy yellow, green and orange display
handkerchief, and ... arranges it in his friend's jacket pocket so as to
stick out in three points." I'm not totally clear on (1) whether he is
at this point wearing Tantivy's Norfolk jacket and (2) if so, is he
putting the handkerchief in the jacket he's wearing or one that
Tantivy's wearing?
