She did work for British European Airways, the Post Office Savings Bank, M&S Trust House Forte and Pall Mall cigarettes – and probably a few others. Her most famous mid-century poster illustration work is for the Royal Blue Coach Services.
Daphne Padden died in 2009. You can see more of her amazing mid-century posters at Quad Royal. Any of these vintage posters would be a great addition to a travel-themed nursery.
