I'm working with stamp packet of TURKEY 500 different.

It's been a long time sice I last worked with stamp packet. How happy it is, though it cost only 3 cent per stamp. I think it's a fun of philately! How can I tell this fun to Jr. philatelists? I'd like to write an article this time with this mind.
Shown photoe is the result I classfied stamps with the philatelic classification of Stampedia Turkey Catalogue.
