I thought this was interesting.  Not cheap, but quite a bit of information on items related to our hobby.

I've seen that on eBay. I was tempted to buy it but as you said it ain't cheap. I did a search on eBay for "telephone stamp" and there seems to always be a few.

Sometimes the seller has telco stamps for sale

Greg, do you collect the NET&T ones?

[Sargeguy]

I have bid on a few but I've never won any.
