I have a funny feeling you are out of luck. With the new draonian US regulations selling, sharing or doing anything other then possing them is highly illegal in the US, unless you can get someone to post them from outside the US to a server outside the US.

As I recall they were published by Harmony But with the new regs I doubt they would sell them to you even if they had copies.

Probably your only chance find them in a store that sells old porn, usually in packs, some where in your neighborhood. But if they arn't already these will be a thing of the past too.

These were great magazines and still in demand today. You might look at the site for some new favorite "LOVE Bondage" pictures.
