This is one of my very first drawings. I won’t even hint at how long ago that was. I used to use a rapidograph, one of those dreadful technical pens that clogged up if you didn’t use them on a daily basis. Extra fun - you got to spill indelible India ink all over the place when you tried to refill it. This was before the widespread use of felt-tip pens. Actually, I loved my rapidographs. I think I’ll go up in the attic and see if I can find them.
I have another painting that REALLY fulfils the Balloon theme, but since I used it for an earlier IF post, I figure it’s disqualified. Be that as it may, here’s a link to Murble for those of you whose curiosity has been piqued.
