Number stamps 1876 with a new look in 2020
The Hague, October 16, 2020. PostNL is issuing a stamp for the Day of the Stamp. The Day of the Stamp would be part of the POSTEX 2020, but unfortunately this fair cannot take place due to the corona crisis.
The Day of the Stamp is a regular part of the annual POSTEX in Omnisport in Apeldoorn. POSTEX is an international stamp event with exchange fairs, exhibitions and other special gatherings. Although POSTEX 2020 is canceled due to the corona crisis, PostNL is still issuing the Day of the Stamp 2020 stamp sheet October 16th.
½, 1, 1½, 2 and 2½ cents
The Postage Stamps Number Type 1876, also known as the Number Stamps 1876, were 
given low postage values to encourage the sending of newspapers and other printed matter by post. Based on a design with a large value figure, Joh. Enschedé & Zonen from Haarlem 144 years ago a uniform series with denominations of ½, 1, 1½, 2 and 2½ cents.
Rotating figures
Sandra Smulders from Gouda has redesigned and rearranged the graphic elements from the Number Stamps 1876 for the design of the Stamp Day 2020. For example, the value number 1 from one design has been rotated 180 degrees with respect to the value number 1 from the other design. Other elements from the numerical stamps are shown in a similar way, both in position and use of color.
Contemporary but respectful
Sander Smulders brought the design to 2020 in all kinds of ways, with respect for the original postage stamps from 1876. For example, the circle in the middle was given a shadow border, creating depth and color difference in the background. Gradients, multiple layers, depth, shadows and a lot of detailing were also used to bring the design up to date. That was also possible, says Smulders, “because the current techniques are many times better than they were then. In this way it has become a contemporary stamp sheetlet, while you can still clearly see what it is based on. ”
