15 300 Unique Drawings

Bob organised 15 300 of his drawing into 50 envelopes. If, as I am assuming, he did this in chronological order the photo below is of  the 15 251st to 15 300th of the drawing he considered worth preserving.

We have not tried to interpret the images or set their orientation in this first look, simply copied then as they were placed in the envelopes.  Pictures must be read in groups of four starting from the top left and moving to the right before moving to the next row to give their order. Within each group they run clockwise starting at the top left. The right hand side of each picture was at the top of the envelope.
