The pages are the original Minkus quadrille from the 1980's to the 1990's. When Minkus was bought out the purchaser kept publishing these pages and finally changed them to black ink and really dark quadrille. They sucked. I finally used them all up and had my own printed with a very simple border in dark gray and a light gray quadrille. Needless to say I don't think I will remount everything.
Posted by Philatarium Jerry, what is the reference source you're citing from? Looks really good.
There are 2 standard detailed Colombian catalogs that most use. They are:
Catálogo A. Barriga Especializado 1980 Published in Bogotá, Colombia by Alvaro Barriga
Last really detailed is 1980. Mine has seen a lot of use and is falling apart after 20+ years. E-mail me off-line and I will give you his e-mail address. He may still have some of the 1980 issues. I have known Alvaro for 20+ years and he is real nice to work with. I was buying some things from him but since he no longer has a US bank account it is mostly Paypal which I do not use. I need some items so I'll have to send some money to my wife's cousin and have him go to Alvaro's store and pay him.
The second catalog is: Catálogo Historico Filatelico Edicion Especializada 1984 Published in Bogotá, Colombia by Leo Temprano
I only met Leo one time so I do not know what his policies are. You will have to look up his contact info.
Don't bother with any catalogs after 1980 or 1984. After that they are no longer detailed. I assume that you can read Spanish as they are both in Spanish.
There are other books for Airmails. If interested I can send, or list, the names of them.
I forgot to mention. The data in a table row is actually written under each mount. I use a drafting pencil sharpened to a real fine point to do any write-ups. In some cases I did a page title with ChartPak lettering. It was too much work for each stamp write-up and besides it would make the page look "messy". Also I have remounted pages and I would have to redo all the lettering, if I can find the letter sheets (after years I still have some ChartPak 10pt Helvetica). Today, with a computer, it is a no brainer.
Jerry love your stuff.I also am huge fan of quadrilles,the only way to go if you specialize.If only I had started with them instead of throwing $$ away on supplements for years and years.Would love to see more of your collection.
As soon as I can spend a little time in the library I plan on showing some early Colombia Airmails. Right now I am using the scanner station in the library. It works out pretty neat for now as I get a 2 hour time limit at the station.
In reference to quadrilles. I started collecting with the Scott Modern Album and a Minkus Worldwide post binder. There was a gentleman in my hometown, Bangor, Maine, who was a dealer. He took kids from the school stamp club and gave us instruction at his home on Saturdays. He taught us just about everything and was a mentor to us. After "class" we were allowed to purchase stamps from his stock at a discount. An expensive stamp was a nickel, considering most weekly allowances were 25-50 cents a week. He advised us to "throw away" the albums we had and use only quadrille pages. Specialized or Worldwide made no difference. I found that of all the quadrille pages available, at that time, Minkus quadrille pages had the largest mounting area. So, I have been using quadrille pages ever since. A year or so ago I worked with a local "mom and pop" printer and had my own quadrille pages printed. The hard part was to get the point size of the grid so that there were an even number of "boxes" vertically and horizontally. It makes laying out the stamps easier.
Jerry, I know others will laugh but I use a HP all in one printer scanner copier.It was dirt cheap like $35 and takes the cheapest ink on the shelf at Walmart.I've been plugging away with it for eight years and my wife uses it for inventory at work.It has probably printed 100,000 pages and still going. As we are both semi retired we don't need fancy or big just usable and this fits the bill.I should have met you thirty years ago supplements are like $20 per year and I only stopped buying them five years ago. 25 X $20 = a lot of stamps
