These are actually wrappers onto Escher drawings. Make use of the DDF classes to do useful things with them. For now, creates a tree of the Escher records, and then creates any PowerPoint (hslf) records found within the EscherTextboxRecord (msofbtClientTextbox) records. Also provides easy access to the EscherTextboxRecords, so that their text may be extracted and used in Sheets
