The VFW or Legion will probably pay for their own banners, and be happy to have you fly them.
My past experience is to have a generic banner, which does not key on any single event,
as they are much more usefull.
Any advice that you require, just PM me, and I will be more than happy to assist.
Remember, we have done this more than once! I'm happy to share.
Note: measure you bed, and also the spacing of the bows.
This will tell you where you want the tie off grommets.
Talk nice to your Legion, and good things can happen ...
our Branch has found us to be the most effective advertising that they have had in living memory,
and to that effect, they volunteered to subsidise our fuel budget! Woo Hoo!!!
