Is it possible to get the PGP public key from PGP message?

Is it possible to get the public key from PGP message in PEM(Base64) format? Here is the message:

I sent this to someone and I was just wondering what if someone other than us knows the PGP message and wants information like the recipient's pubkey or other info.

• What constitutes "knowing the recipients pubkey"? PGP will include a key fingerprint. It does not include the entirety of the person's public key, so their key cannot be derived directly from it, but public keys are intended to be just that, publicly known. If an attacker has intercepted the public key as it is being transmitted to you (which it is assumed they can, as it is public), they will be able to match the public key to the message you send from the fingerprint. It does not directly include the full pubkey, but it has identifying information which could easily reveal the pubkey. – arcaynia Jul 14 '20 at 16:30
• Almost dupe security.stackexchange.com/questions/199427/… where it is considered ontopic, and more linked there; several previous Qs here have been closed as offtopic, and at least one I know I answered deleted. – dave_thompson_085 Jul 15 '20 at 3:29

No, the PGP format doesn't contain the public key of the sender. But it does include a key ID of the key (pair) so that you know which private key to use to decrypt the message. It is rather easy to verify this by reading the OpenPGP specifications which defines the packet format(s) used. Or you can take a look using gpg --list-packets --verbose.
• The long (64-bit) keyid, not the full fingerprint. But that is enough to check keyserver(s). For the message posted, pubkey enc packet: version 3, algo 1, keyid 55B6E24604AE28A9 which one of my configs finds as the encryption subkey for pgp.EncryptedChat <a1mtarabichi@gmail.com> – dave_thompson_085 Jul 15 '20 at 3:33
