Overall I would state the E91A is tougher to come by. Here is a link to an article about the E91 sets, and I have included scans of the E91A Taylor and from a couple different issues to highlight similiarities (scans are from cards on the web). Taylor falls in the category of unknown photo source, but decent facial likeness.
