According to "Eric King's Guide To Psychedelic Poster Collecting", this poster was printed just once, prior to the shows.  We have never seen any evidence, nor heard of anyone in the hobby that disputes this claim.  It appears clear to us that this poster was not reprinted.  The original/first print BG 14 measures approx.  14" x 20".

The original handbill measures approx.  5 1/2" x 8 1/2", and was printed prior to the shows on thin paper stock.  For some unknown reason, this image was not reprinted by Bill Graham as a postcard, so if you are collecting the Fillmore "small" images, the handbill is your only option on the BG 14.

It is worth noting that this was the first appearance by Janis Joplin at the Fillmore.  She joined Big Brother a week or two prior to these shows, making BG 14 her Fillmore debut.  This is also just the second Grateful Dead appearance at the Fillmore.  Quite a bit of history is associated with these shows.
