Talk:Sleeper wall

Proper sources?
Recently there was a revert on the edits claiming it was linkspam, but I do not think it is since none of it is involved in product promotion. Rather the version the other user tried to revert it to was rather confusingly insufficient. However, I do think it is important to find better sources, possibly from encyclopedias used by architecture majors.Any help regarding this?Waltzingmogumogupeach (talk) 13:14, 2 July 2022 (UTC)
