New Jersey dealer items Polkowitz

[rich neary]

I grew up in NJ and the local Cadillac dealer in Perth Amboy was Polkowitz Motors.
Polkowitz closed many years ago but i have fond memories of the many afternoons spent as a kid examining the new cars on the show room floor.
I'm looking for any items from this dealership.
My Caddymania goes back many years and through many cars. Latest is my 1957 Fleetwood.
Thanks in advance,
Rich

Polkowitz eventually became Polkowitz-McGuire and then just McGuire, after relocating to Woodbridge, which is still in business today.  It may be a long shot but perhaps they still have old items from the Polkowitz days.

I'm not in NJ any longer but next trip up to see family will look into it.
Meanwhile I'm still looking.
Thanks
