Proofs, Essays, Progressives Or Waste ?

Hi,
I would appreciate some advice if possible ?
I have inherited a collection/accumulation of material and some of it I have been told is from the Format International archives I have been made aware of the company history and because of that would like to know if there is a market for this material and if so where or who best to take it to for sale.
Thanks

Format International archives? perhaps they meant to say 'someone's garage'?
If you are aware of the company history then you know that the material is highly questionable (at best). The 'go to' place for selling questionable material is ebay; assuming that you don't mind parking it on people and can sleep at night afterwards.

I believe that folks can collect whatever they desire. So I do not think there is an issue if it got listed and described accurately (as questionable material). But unfortunately much of the time this material gets listed as 'modern rarities' or is left undescribed and 'buyer beware'.

Are these originals from the Format International archives or modern fake reproductions? Just being facetious.

For those of us, ignorant of Format International.........

understandably a touchy subject, I have shown some of this stuff to a reputable auction house who are pleased to include it into there auction under the title of Format Int stamp proofs. I asked the question on this forum to confirm I am making the right choice.
Thank you
