I think you’re right about being hand-drawn, The s’s are tilted slightly and the smaller a is a different shape slightly. If you have any idea how old the design is, you can search for that time period. I would guess 1900s. I have a feeling that P is not going to be easy to find.

It dates from the 1880’s:

History of ’Bubbles’. No history of the lettering unfortunately.
