I found this last night while going through some pictures.
I thinlk it was probably in the early 80's but not sure where.
The one thing that makes me think this is the sign on the Helium Tank.
Your Name on the Silver Balloon.
It used to say FREE but certain folks thought it meant a free balloon, so we had to change it!
Also notice the barrel out in front, we always had a 1.00 barrel back in those days!
