This is certainly one of the classic images of the psychedelic era.
A very cool/colorful sixties image that features two colorized photos of
Quicksilver Messenger Service (the bottom one being upside down).
The original/first print poster was printed on very thick/sturdy paper
stock, which matches the paper stock that was used to print the original
postcard. They were most certainly printed on the same proofsheet,
prior to the shows. In addition, the orange ink that was used to
print this poster is a pure orange (this also matched the original card).
The second print poster was printed on a much thinner paper stock than the
first print poster, making it somewhat "flimsier". In addition, the
orange ink that was used to print the second print poster contains much
than the orange ink used for the first print. I would actually call
it yellow/orange, not orange. As is the case with the first print
poster, the second print poster contains the notation "No. 53-1" in
the lower right corner, however it is NOT an original/first print poster.
There are two variations to the original postcard that were printed prior
to the shows. One has a place stamp here back, the other a bulk rate
back. If you buy a FD 53 postcard from the website, we will ship you
a place stamp
here backed card. If you are interested in a card with a bulk rate
back, please send us an email or give us a call.
