While going through some old props that I haven’t used in awhile, I noticed a trick that I received about 14 years ago from JB Bobo called Bobo’s Jumping Jack. It is basically a Tarbell frame effect. The box is intact and autographed by JB Bobo himself. I was just wondering if anyone knew the worth of this. Should I put it in a glass case or is it ok to leave it displayed on my collectors shelf. Thanks ahead of time for your help.

closeupmaster: looks like no one really knows the answer to your question and I wish I could help but unfortunately, I am not familiar with the effect. You may want to contact a used magic dealer like Mario Carrandi or Ron Alesi. They may be able to help you. A good dealer may also be able to assist.

Ask John Mendoza at "flinner@concentric.net". He is very good as well on pricing. I can't get Mario to ever respond to emails.

This should sell on Ebay for between $40 and $150. It is a giant slat frame with Jacks and number cards.

Did you ever sell this item?

No I still have it.
