Skylab Stamp

So I got this package in the mail the other day (from a small mail order company). It had a Skylab stamp on it! It was only a 10 cent stamp (actually it had other old 10 cent stamps on it too) so that makes it about 20 years old. It was strange, I assumed if they had hundreds of these laying around it that it’d be better to sell them for a few pennies more than to actually use them. And it’s a nice Stamp I’ve always liked the way that one looked so it really caught my eys. My purchase was a $100 upgrade to something I had already purchased preciously so I’m assuming they weren’t scraping for loose change to mail this. It just struck me as strange…
