Have a happy birthday de bobo

This interesting birthday wish arrived in the mail. Note the following: The greeting is written on a dirty napkin.  Envelope and card are attached below.  Thanks to CA I literally laughed out loud.
An envelope worthy of the Zodiac killer, with worse spelling.  Allam DeBOBO! The coffee stains are a nice, artisanal touch
The napkin birthday card:  Dark streaks are sticky jelly stains from a PB & J sandwich
