#10-2007: Like many countries around globe, Serbia this year participated with WWF issue of protected animals, woodpicker, nice design, 4 value set plis one tab on middle, aditional expenses for collectors if want all tabs included in collection, because this sheet is from 5 set, with tab on middle composing one complete picture. Date of issue is April 18, 2007, and set alone can reach 3-4.00 euro (without tab, and strip with tab even more), FDC go for 4.00 euro, and sheet of 5 set absolutely will go for 30-40.00 euro.
#11-2007: commemorating "Table Tennis" issued March 23, 2007, to celebrate European Table Tennis Championship held in Belgrade, and issued in single stamp plus sheet (block) together, where prices for both will reach 2.50+ euro, and FDC can be sold for 4.00 euro, but sheet of 8 plus tab can be high as 15.00 euro.
#12-2007: standard issue for "Nature Protection" (even that Serbia is rapidly cutting forest, for sale on German market), two value set, design with too much color and detail, I personally don't like it, and think that Serbia Post can donate money to Nature Protection Offices, instead of printing this issue. Set of two value, issued on April 20, 2007, set can sell for 2.00 euro, and FDC can reach 3.50 euro, but sheet of 8+tab will have good prices of around 18.00 euro.
