I have a Firefox extension that uses a bunch of different reverse image searches, like this:
View attachment 120600
It'll open a new tab for each of the different reverse image sites.
One of the hits came back to one of the pictures but it was cached and not viewable on the internet. But I could see the title of the LL ad that it hit on and it was Lisa - Icon, like so:
View attachment 120601
I then just perb searched "lisa icon" which then led me that post.
