In Revisiting Autograph Identification Questions the community determined that for a range of reasons, that type of question is off-topic.
Since that time, although we continue to receive new questions, they are fairly rapidly closed, with most close-voters including a personal canned close reason directing the new user to the meta questions on the issue.
However, we also have a number of questions about identifying other memorabilia. While many are historic and this category of question is rare by any standard, they bear many of the same features and therefore many of the same problems.
They often lack sufficient detail to determine "the" answer, making them immediately either unclear or sometime too broad to be answered
They almost always ads localised and idiosyncratic to a specific user, and are very unlikely to help others in future
They almost always require images as the primary or even sole source of information, making them unsearchable in the current Stack Exchange system
This broader category of question, including autograph identifications and memorabilia identifications, suffers from too many issues that are not resolved. It is proposed that they also be deemed off-topic, and unanswered or downvoted or new questions be closed.
