Rob postedthe new image with the following caption:

Hi there.! Hope you all will have a great weekend.! Here is some extra candy from one of our sponsors to enlighten your day… ._.

An identical copy of the image was posted to the brand new official-art channel when it was
made four days later:

1) 43 34 33 44 11-XXV

Snippets of numeric text were found throughout the image (1e, 1c, 1a, 1d, 1b). The string is completed by arranging the snippets which contain purely Arabic numerals from their placement in the image left to right and placing the snippet with Roman Numerals at the end.

Using tap code (aka knock code) to decode the Arabic numerals, and replacing the Roman numerals with their Arabic equivalent results in the solved string “SONATA - 25”

2) Ludwig signature snippet

This is Beethoven’s first name from his signature:
LVB signature | 1000
The identity of the signature was not discovered until a second snipet of the signature was found when Ospuze_Candiii was released.

3) Two tick marks
