Pick A Topic, Get A Poem

I took the photograph on the left at the First Friday Art Walk on Santa Fe Boulevard here in Denver the other evening.  The man in the photograph, typing away on an old typewriter, will write a poem for you on your topic of choice for a donation.  I have also seen a young woman sitting at this same typewriter on the 16th Street Mall on the weekends, with the same, handwritten "Pick a topic, get a poem" sign.  I assume they are a couple, and are somehow trying to earn a living doing this.  Although the woman standing in front of him seemed  pretty enthusiastic about it, I would have to think this would be a tough way to make a buck. Hopefully they both have regular full time jobs - possibly writing greeting card verses - and this is just a hobby.  If not, their next business sign will say "Will write poems for food."
