This brochure came in several bindings throughout its life. The first two editions in 1961-62 had spiral metal binders while all later ones had plastic comb binders.
The earliest edition available at the E-Type launch was printed before the road tests were available. So a true 'Launch' brochure does not have the road test reprints in it and are thus comparatively rare. You can spot genuine versions of this first launch edition by the fact that page 8 (captioned The Jaguar E Type G.T. Open Two Seater) has the 'Printed in England by Adams Bros and Shardlow Ltd., Leicester' imprint at the bottom right hand corner. The later editions have this on page 12.
