Offering what appears to have been a band know as "Steve Wilson's Rhythm Jesters" advertising booklet for the gigs they played ' Must have been handed out during their performances. I am only guessing this was back in the 60's because phone number shows no area code or zip code for the mailing address. Either way its kind of cool if you're a collector of such Paper Ephemera and if not who knows maybe you're related to or familiar with Steve or his band members.Finally I had a small rock & roll band back in the early 60's and this was stuck in my sheet music folder - you take it from there.
