I doubt any readers remember the great pre-WWI Zeppelin races, or were told about them by their families. The last big one, in 1913, had its finishing line at the New Brighton Tower* - another historical topic lost to living memory. Colin has used this event to design and print some commemorative postal labels. We haven`t seen all the variations, but a glimpse of a small part of a sheet shows that a number of background colours were used, each with a range of text colours. The main image of the finishing line with all the competitors circling is variously tinted - and inverted. Like the Black Cat labels, these were produced as test pieces to see which colours worked well as text and background in the finished product

Look out for any of these - all are probably different. Different greens and maroons, different text colours, images in various tints or monochrome; sometimes inverted and sometimes mirrored. After the initial unperforated examples, perforated stamps began to appear - some in the same colour combinations even.

* New Brighton Tower, situated on the northern tip of the Wirral peninsula and overlooking the Mersey towards Liverpool, was even taller than the Blackpool Tower. Unfortunately it lasted but a few years before it was damaged irrepairably by high winds and was dismantled. The ballroom however stayed on until the 1960s. The Beatles played there more than once, but it was demolished after an arson attack.
