Back when the old Horslips GB was admiring Aidan's stamps and his Horslips feature, I pointed out that Horslips COULD be on a stamp quite quickly.
The USPS has partnered with Stamps.com and offers a service whereby people can make their own legitimate postage.
The idea being for weddings, baby announcements, Christmas cards, etc. you might like to have a stamp of your child's artwork or vintage photo or whatnot. But it seems I could use a few stamps for all of my postal correspondence -- "Letters from Home" you could say -- to my Horslips friends.
Seems a natural then, that I would use the cover art from The Man Who Built America. Unless anyone else wants to suggest a theme?
