Someone else help this anon clean this up for better visual:

From LB https://8kun.top/qresearch/res/12582248.html#q12582743

Assuming post 12582743 is correct, and Grant's Tomb is the Keystone:

Synonyms for Keystone: basis, principle, foundation, linchpin

Searching for Q Crumbs with the word KEYSTONE, there are 9 as follows:

128

133

140

167

251

262

270

448

2633

IMO, the most relevant one is Crumb 128, part of which is also posted.

Need help deciphering and analyzing. Kudos to the anon on the previous thread.
