P. R. Of China 2002 And 2003 Year Issues:

Have a little time, so I'm going through the stock of materials from P. R. of China!

I see that 2002 and 2003 were quite successful for them, both in terms of the number of issues and the quality of design and printing.

Comparing it in catalogue (Michel and Stanley Gibbons), I see that prices are adequately placed, not too high and still affordable for this kind of material.
I haven't checked, yet, in Scott, but believe it is same as in two mentioned.

So, my personal opinion is, that it is time to fill gaps in album!
