1960s grooviness

I had TOOOOO much fun with these envelopes for a 1960s party - and how kind of the post office to have Janis Joplin stamps available!

This is for a long term client who hires me every year to work on her husband's birthday party.  She always has such creative ideas and lets me cut loose, I appreciate that more than I can say!  Lettering is done with Sakura flourescent Gelly Roll pens.
