My name is omar wassef, I live in Houston Texas. My partner in development of this website is Volker Kleiner. He lives in Essen, Germany. We developed this website to attract other collectors like yourself. Your post tells me that we have finally succeeded. Thank you.
We are looking for the seals which are marked in red. There is a section of the website classified by town-names, alphabetically. The seals we have more than two are shaded in blue. They are available for a swap. The ones shaded red are ones we do not have and we would like to, at least collect scans thereof. If you have scans - send them and we will update the site.
I am excited about your post concerning type I seals. We have been looking too, they are hard to find. The only place I know of where there is an extensive collection is at the British Museum, we contacted the museum and they told us that, later this year, the so-called Tapling collection where these seals reside, will be made digitally available on the internet. Once we receive it we will post on the site.
We hope to correspond with you often and to collaborate with you on improving the site. Best Regards, Omar
