It looks like you have a pre-existing overlay request on the second page that was already locked. Per the art market rules you need to wait until all requests for the same type reach the third page before they can be requested to be locked. As such, I’m going to leave this one open. If you have another artwork buying request, please edit the existing thread first with new information instead. Once it’s reached the third page, it can however be requested to be locked.

Post locked as rules have been amended to second page locking instead.
