There is a good article in this month's issue of The American Stamp Dealer & Collector on the TASCO Educational Booklets. If you collect these or just have an interest in them I recommend getting a copy of February's issue. I know Glen Estes has a web site with some information. http://glennestus.com/tascopics/Tascobooklets.html
I found out that there is a handbook of TASCO products. There was also an album but I am unable to locate that.
Don,
I completely forgot you posted my booklets on your site, I must be losing it. I plan on ordering the Tasco catalog from Eric Jackson. Do you have any information on the album?
Randy,
I agree that The American Stamp Dealer & Collector is one of the best Philatelic magazines available. I usually read most articles. We talked about this before and I also like Kelleher's Stamp Collector's Quarterly, many of the same authors. La Posta is another of my favorite magazines. All three are a must if you have an interest in U.S. postal history or collecting.
