1970 Postmarked Envelope with Apollo 8 Stamp

Got this vintage envelope from 1970 with a cool Apollo 8 'In the beginning God...' stamp on it. It's postmarked from Normal, Illinois and addressed to San Antonio. The stamp itself is a 6 cent commemorative one from 1969. Definitely a neat little piece of postal history or for someone who likes space memorabilia. It's got some wear and tear on the edges as you can see in the pics but the postmark is pretty clear.
