He probably created and posted the card to himself as a practical joke on the postal service, since the image is a caricature of workers in the post office. In 2002 the postcard sold for a record £31,750.
The bulldog has been on many a postcard since those early days and most were early drawing sketches and if you were of money you could afford to buy an early colour piece also used in advertising postcards too.
The bulldog postcard came into popular effect during the Great War and WW2. There are a few stories to why the bulldog was used and many say it’s because Winston Churchill famously owned bulldogs and also the bulldogs character was the same as England wanted to be seen and that was strong stubborn and defiant to the enemy.
Monies made from wife’s buying postcards to send to their loved ones fighting in the war or even to send domestically.
Some postcards can be seen in poor taste due to the subject matter but on the whole they make up a portion of many peoples collections.
Investable postcards are 1914-1918 for obvious reasons but earlier ones are just as valuable if not more so.
