You have jogged my memory about Jim Wieland. Wasn't he a friend of Bob Brennen's? It seems to me I connect those two together. Could be wrong. I remember him from Hasbrouck Heights Toy Show, in North Jersey. You are right, regarding him sleeping in his car. He went so far as to sell out of his trunk, so he wouldn't pay for a table at a show. I only saw that once or twice.
As far as I remember, he traveled all over Europe, or South America, buying odd ball toys, that no one else had. I never dealt with him. He had a lot of cheaper toys that I had no interest in.
I remember receiving these toy lists, you could hardly read, A thousand toys were squeezed into 3 sheets of paper. I had heard he would ship out damaged stuff and then give you a really hard time trying to return them. He would wear you down, so you would just give up. That is hearsay, it didn't happen to me. Please correct me, if I am wrong on any of this.
