Vintage Triumph Gyronaut X-1 Poster Bonneville LSR nos ?

This small poster measures a bit larger than 18" x 12".  I found a few of them at the bottom of a distributor inventory I bought years ago.  I believe it was produced to commemorate the Bonneville record attempt (and success) in 1965 by Triumph dealer Bob Leppan.

Condition appears excellent; no rips, no tears, no trauma.  Quality of the print isn't perfect/perfect, however.  There are several very tiny flaws to the photo print itself, that show up as little white spots towards the bottom, like this was an amateur 35mm photo blown up to larger size.  These tiny flaws aren't consistent from one print to another.  I don't have an explanation for this.  You'd think Triumph would have made them with more care.

Still, the thing is GORGEOUS!  It has that perfect vintage feel and look.  I know I'm being too critical.
